C++17 support in gcc is now quite complete, has been out tested by some users since gcc 8, so shall it be switched on by default in gcc 10 ? Or gcc 11 ? However I fear doing that may break some tests in the testsuite, I hope not too many. Cheers, Romain

Hi Jonathan,
FYI, it seems that with python 3.12, the bits "Use raw strings for regular
expressions"
seems to fix the following new Python warnings:
/opt/1A/toolchain/x86_64-v23.0.19/lib/../share/gcc-13.2.1/python/libstdcxx/v6/printers.py:1273:
SyntaxWarning: invalid escape sequence '\d'
self.typename = re.sub('^std::experimental::fundamentals_v\d::',
'std::experimental::', self.typename, 1)
/opt/1A/toolchain/x86_64-v23.0.19/lib/../share/gcc-13.2.1/python/libstdcxx/v6/printers.py:1302:
SyntaxWarning: invalid escape sequence '\w'
x = re.sub("std::string(?!\w)", s, m.group(1))
… (snapped, there are a bit more than that in total).
How ok would it be to backport to the branches still maintained the "raw
string" fix,
in order to avoid deprecation warnings as soon as people use gdb with python >=
3.12 ?
Thanks,
Romain

Cool thanks ! ;)
In the meantime, in my own toolchains I have silenced (without fixing it) the
warnings
with this simple patch (in case anyone else wants to quickly get rid of it, but
it’s not
really a good long term workaround).

[stdc++] Mark global new/delete operators as weak symbols
Hi, According to the C++ standard §17.4.3.4(2,3) the global new and delete operator implementation can be replaced by the program. For example, tcmalloc does redefine them. On ELF targets, it is currently OK if you link libstc++ dynamically. However, if you try to link both tcmalloc and stdc++ statically, then the linker will complain about multiple symbol definition. This patch fixes this by marking the global new/delete operator as weaks for linux. I may be extended to all ELF targets. Bootstrapped and tested on SLES 11 SP1 x86_64.

I don't know if this is an issue on > libstdc++ side or clang++ side. __is_same_as is not implemented as a compiler builtin in clang++ unlike g++, thus the error on clang 9.0.0 side. It looks like current clang trunk doesn't define __is_same_as either. Until clang implements this support (if it ever will), usage of __is_same_as in libstdc++ shall be conditional, only when __has_builtin(__is_same_as) is true (however that would require that gcc implements __has_builtin, as implemented here: https://gcc.gnu.org/ml/gcc-patches/2019-10/msg00062.html ) Cheers, Romain
[Driver] Add support for -fuse-ld=lld
Hi,
I would like to raise again the question of supporting -fuse-ld=ldd. A
patch implementing it was already submitted in
https://gcc.gnu.org/ml/gcc-patches/2016-06/msg01722.html by Davide
Italiano. This patch still applies correctly to current trunk. I am CC-ing
the original author and re-posting it here unchanged for reference.
I think we can consider this patch as relevant despite the goals and
licence difference of LLVM vs GNU, based on what was written by Mike Stump
in https://gcc.gnu.org/ml/gcc-patches/2016-07/msg00157.html
Back then, the technical problem raised by lld was reported as
https://bugs.llvm.org/show_bug.cgi?id=28414 now closed. In this bug, every
reported problems have been fixed except the last one. H.J. Lu mentions
this last problem (lld does not produces symbol versions predecessor
relationship while ld.bfd and ld.gold do, which seems to be a decision
taken on purpose and advertised as a harmless change) as being one reason
against supporting in -fuse-ld=ldd in gcc. Is it still the case today, and
if yes, why ?
Is there any other reason why -fuse-ld=ldd shall not be supported by gcc ?
Cheers,
Romain

Hi,
This small cosmetic patch should address it. I don't know how much spaces
should be used to indent the second and third lines in the if condition,
this of course can be changed if it doesn't follow the gcc guidelines.

For now, plugins can't compare types. This patch allows
c-tree.h to be installed as a plugin header, allowing
plugins to see "comptypes" (among other things).

[MELT] Add a few tree primitives
Hi,
I added a few primitives about trees, plus a string_to_long
conversion primitive and a foreach_pair_between iterator
that allows to iterate between two pairs of the same list (and
thus iterate on sublist).
Note: again, it's a git patch for Pierre until Basil returns.

I tried to built two different revision this afternoon, each time with an empty
build directory, and none worked (same error as Pierre got, it stops at Melt
stage 1). IIRC the last one was at revision **162 or something near this one. I
do fully bootstrap GCC unlike you, but the error occurs at GCC stage 1, so GCC
bootstrapping might not be the cause.

I've made a few changes so that Melt bootstraps. But it still fails at
the final check-melt-runtime for a simple reason: Melt won't load
modules as we don't give it the melt-workdir where all *.so reside.
I realized that all those recent changes had made the melt-modules
directory completely useless as you always look for
my-module.MD5.FLAVOR.so that are in melt-workdir, and bypass the
melt-modules symlinks. I don't really know what exact behavior you are
expecting from the melt-modules, melt-workdir and melt-tempdir
directories so i don't really know how to correct the issue.
Find attached the log for check-melt-runtime, but it might not be
useful, i already gave you the reason of the error.

This new build behavior broke former plugins built with gcc. Indeed,
all cc1 function symbols are now mangled and thus with the current
trunk, plugins should also look for mangled symbols (and so built
with g++).
What's the new GCC policy about that ? Do plugins have to be built
using g++ only, or does the plugin developer have the choice to
use both gcc and g++ according to it's need (at the cost of adding
extern "C" {…} in almost every headers to forbid mangling) ?

Adding extern "C" to a few > selected header files seems fine. Adding extern "C" to a small set of files doesn't make sense to me. When working with real-world plugin, you will certainly end up calling many different gcc primitives coming from a wide bunch of header files (which for most of them don't use extern "C" for now). This hack should be applied to all of the plugin visible files, or none, but not to just a few when someone needs it.
[Patch] Properly find getopt system declaration
Hi
Thanks to the recent changes made to stage 2 and 3 (now built with g++),
i noticed a little error in the configure script that tries the
system getopt declaration. Indeed, if your system defines it in a system
header file named "getopt.h" (for example /usr/include/getopt.h on a Red
Hat 4 configuration), the configure script will incorrectly load
/path/to/gcc/src/include/getopt.h instead, and thus find no getopt
declaration.
This can be solved by changing the appropriate -I${srcdir}/../include by
-iquote ${srcdir}/../include. I added a configure check to verify that
the compiler accepts the -iquote switch (and fallback to -I otherwise).
Note that this only solve the getopt case, but -I is certainly often
misused (instead of -iquote that would prevent error with system header
having the same name than gcc header).
The attached patch has been tested for regression with a native x86_64
bootstrap.

[PLUGIN] Fix PLUGIN_FINISH_TYPE
Hi,
This patch solves some lacks with the PLUGIN_FINISH_TYPE event
triggering. For now, both C and C++ parser won't trigger it for enums or
for typedef. In C++, when a struct, class or union declaration is parsed
(without definition), the given event data is an error mark instead of
the parsed type node.
Bootstrapped and tested on x86_64.

I just checked again, and PLUGIN_FINISH_DECL is triggered for a
typedef in C mode, but not in C++ mode. I'll patch that.
When i recontributed the PLUGIN_FINISH_DECL patch from the original
Brian Hackett, i didn't exactly checked what may or may not trigger
this new event. I know for example that declaring a function triggers
this event, but defining it does not.
I don't really know when those event should be triggered, we should
clarify the meaning of those.
According to me:
PLUGIN_FINISH_DECL should be triggered anytime the parser parse a
declaration (which includes declaration + definition of function,
typedef definition, namespaces, ..., all DECL_P trees built by the
parser).
For, PLUGIN_FINISH_TYPE i don't really know it means a new type
declaration (or declaration + definition) or if it means usage of a
type (in a function prototype, the type of a local variable. I would
rather vote for new type definition (including typedefs) but for
special cases of struct, you can declare and use them at the same
time:
#include
struct my_struct x;
struct my_struct *my_function ();
struct my_struct {
int field_1;
int field_2;
};
struct my_struct *my_function () {
>---return NULL;
}
which GCC accepts even with -pedantic.
That's why in this patch i launch a PLUGIN_FINISH_TYPE event every
time the parser meet the "struct" keyword.
So, what the real meaning of all those events ?

Ok, so it only involves struct, unions, enum and class declaration /

Personally i don't need to catch all struct uses, but i need to catch struct
declarations.
I want to apply some __attributes__ to a given struct type, for example let's say i need
to mark *struct my_struct* as deprecated thanks to a plugin. I know how to apply some
attributes to a type or a decl. See the plugin (test_plugin.c) and the test files attached.
With test_pass.c, my_struct is declared first, then defined after, applying the deprecated
attribute works.
With test_fail.c, my_struct is declared and defined at the same time, applying the
deprecated attribute doesn't work with the current trunk (and also with my patch).
I got:
test_fail.c:4:1: warning: type attributes ignored after type is already defined
[-Wattributes]
So i may need a PLUGIN_FINISH_TYPE_DECLARATION triggered when the type is declared but
before it is finally defined.
Does two different events PLUGIN_FINISH_TYPE_DECLARATION and PLUGIN_FINISH_TYPE_DEFINITION
make sens to you ?

Re: [PLUGIN] Fix PLUGIN_FINISH_TYPE
Hi, I tried to fix PLUGIN_FINISH_DECL as well to include typedefs in C++. The followings does not currently trigger the PLUGIN_FINISH_DECL (or not in all cases), but should them ? - function parameters (in the function prototype) - definition (with a function body) of a top-level function (while the exact same function definition enclosed in a class definition will trigger PLUGIN_FINISH_DECL) - label declaration - constants defined by enums - namespace Romain.

I may need to apply any type attribute when a new type is parsed, which is currently not possible with the current C++ front-end. Romain

Add __stpncpy_chk builtin support
Hi,
The current trunk have no support for the __stpncpy_chk function. As the latest
OS X (10.7 aka Lion) now defines stpncpy as a call to builtin__stpncpy_chk for
GNUC compliant compiler, the following code won't link:
#include
int main(){
char string[10];
stpncpy(string,"abcd",8);
return 0;
}
Undefined symbols for architecture x86_64:
"___builtin___stpncpy_chk", referenced from:

ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
This patch add support for this builtin.

[PATCH] Fix configure --with-cloog
Hello
This patch fix an issue while building with cloog and gmp installed in
a custom separate directories.
How to reproduce :
- Make sure you've installed cloog and gmp in separate directories
(ie ${WITH-CLOOG-PATH}/lib doesn't contain libgmp)
- Make sure neither gmp nor cloog is not installed in a directory
searched by default by your linker when looking for libs.
- Launch configure script with both --with-gmp and --with-cloog
switch properly set
This result in an unexpected error while configuring: error: Unable to
find a usable CLooG.

I mean, why don't you hook on the PLUGIN_PRE_GENERICIZE event to catch all function bodies, and then compare the argument the user gave you to current_function_name() (that will returns you the full protoype of the current function, ie: malloc full name is "void* malloc(size_t)"). Then, you can store the FUNCTION_DECL tree if there's a match and use it for later processing. That's how i proceed for my plugins. Romain Geissler

[PLUGIN] c-family files installation
This patch add a new exception to the plugin header flattering strategy. c-family files can't be installed in the plugin include root directory as some other files like cp/cp-tree.h will look for them in the c-family directory. Furthermore, i had to correct an include in c-pretty-print.h so that it looks for c-common.h in the c-family directory. That way, headers will work out of the box when compiling a plugin, there is no need for additional include directory. Builds and installs fine Ok for the trunk (i have no write access) ?

You forgot to attach the patch for melt-runtime.c (there is only the changelog) I know your performing some simple static analysis, mostly based on matching some c source code patterns (check that there is a if (fopen_result) just after a fopen.

[MELT] Several build fix
Hello, Here is a little patch that fix build on my red hat system. It should work for both the plugin and the branch version (although i could not generate the new plugin because upgrade-warmelt require unifdef that i don't have on my system, so the plugin version has not been tested directly from the branch source tarball). Please check if it still work for you, i may have broken things ! (this includes @Basile Do not read this until you're back from your vacation. I've corrected the bug dealing with unfound c sources files to build existing module so files I have also added a -Wno-error switch in the check-melt-runtime so that it doesn't break the whole build (as it uses -Werror by default on my system). But this should be only a temporary workaround, as you noticed some days warmelt-ana-simple detects bugs in the runtime, and this should be corrected. There is mostly meltgc_* functions that do no declare a MELT_ENTERFRAME. I don't really understand why and when there is a need for such, so i let you correct that. When it's done, do not forget to remove the -Wno-error switch. The plugin version should now be a little bit more configurable thanks to variable ?= value assignements. In particular, we can use a custom gcc and not the one in PATH, and add some library includes thanks to LIBS_INCLUDEFLAGS (useful when ppl is not in the default include directory for example). I will now try to patch the trunk to build twice and install gengtype when plugins are available. build.diff Description: Binary data build.Changelog Description: Binary data

[PLUGIN] compile and install gengtype, install gtype.state
Hi,
This patch allows a third party plugin to define new GTY-ed types
by compiling and installing gengtype for host and installing gtype.state
in plugin_includedir.
Builds and installs fine on a x86_64 red hat.
Ok for the trunk ?

[Melt] Add coutput argument to translateto* modes
Hi, Melt is creating annoying *.c files next to the .so module file, and i just can no longer handle temporary files polluting my final binary directory. Here is a simple patch that allow the user to give an explicit coutput file path in all translateto* modes. By the way, trying to reach the C sources files and checking their checksum with the loaded .so module just don't make sens to me. This task should be done by a proper Makefile by the plugin developer, not by Melt. Gcc won't tell you that your file.o is outdated because file.c has changed, there is no reason for melt to act otherwise. At least, disable this behavior by default and allow it through a custom parameter. Romain Geissler Changelog Description: Binary data couput.diff Description: Binary data
[Melt] Add some includes to melt-run.proto.h
Hi, I added a few includes i need to define some new primitives. Basile, i included two "c-family/*.h" files, but be aware that currently GCC does not install this headers in the c-family directory but in the directly in the plugin/include root directory with all other headers. I posted a patch some times ago to solve that (because it breaks includes of C++ plugin headers) for the trunk. Unfortunately, the patch hasn't been reviewed yet. See http://old.nabble.com/-PLUGIN--c-family-files-installation-td32038394.html Once again, Debian maintainers applied a similar patch for a long time and thus theses files are in the c-family directory (but only for Debian users).

Re: [Melt] Add some includes to melt-run.proto.h
I have just updated to the latest svn revision, and it seems you forgot to #include cpplib.h and langhooks.h. Note about the c-family issue, you will be allowed to apply it (in the trunk, and then in the melt branch) in 24 hours unless the plugin maintainer block this one. I can't do it by myself as i don't have write access to the svn repo. See Joseph S. Myers post at http://old.nabble.com/-PLUGIN--c-family-files-installation-td32038394.html Romain Geissler

[MELT] Add some utils closures.
Hi I added some new closures i needed for my plugin that i think worth being shared to all melt users. I also removed "string=" and "string!=" primitives, as "==s" and "!=s" just do the same. Romain Geissler melt-utils2.Changelog Description: Binary data melt-utils2.diff Description: Binary data

[MELT] split_string_* functions now take a value
Hi,
I changed the argument type for the cs argument in split_string functions.
Indeed, there is no way to access the boxed string from a value, and sometimes
we can't avoid working with boxed strings. As we can box a :cstring in a value,
split_string_* functions are usable in all cases.
Find attach the patch. Please note that it is a git patch, thus it should be
applied with git-apply or git-am.
Romain.

[gcc 11 backport] Support ld.mold linker.
Hi,
Is it ok to backport small unrisky features to the old gcc 11 branch ?
Here is a proposal to merge the ld.mold linker support which Martin has
pushed in gcc >= 12. It's a cherry-pick of commit
ad964f7eaef9c03ce68a01cfdd7fde9d56524868. Note that it doesn't backport
the gcc build machinery to be able to link gcc itself with mold.
Note: it also doesn't backport Martin's change in the LTO machinery to
support LTO plugin with mold.
Cheers,
Romain
gcc/ChangeLog:
* collect2.c (main): Add ld.mold.
* common.opt: Add -fuse-ld=mold.
* doc/invoke.texi: Document it.
* gcc.c (driver_handle_option): Handle -fuse-ld=mold.
* opts.c (common_handle_option): Likewise.
