[Bug target/36923] Crashes with FPU inline-assembly
--- Comment #1 from ubizjak at gmail dot com 2008-08-03 09:16 ---
Stack asm constraints have some annoying properties. Please note, that in your
testcase, value in %st1 isn't popped from the stack. Also, reverse subtract can
be used to avoid fxch. I propose to rewrite your function as:
static float fraction( float _x )
{
int tmp;
asm ( "fld %%st\n\t"
"fisttp %1\n\t"
"fild %1\n\t"
"fsubrp %%st, %%st(1)"
: "+t"( _x ), "=m"( tmp )
:
: "st(1)" );
return( _x );
}

Basic design concept is that WorldObject implements remote method call
functionality using the "curiously recurring template pattern" to enable
forwarding calls from the generic base class that implements the transport
layer to the derived class.
The specific failure was in forwarding calls to items in a container.
This is emulated here by wrapping a single item.
In the main program there are two forms of the call. In the last
(uncommented) form the member function pointer is for clarity
assigned to a variable (itemfunptr) before making the call.

--- Comment #1 from pinskia at gcc dot gnu dot org 2008-08-03 21:47 ---
Confirmed.
SRA messing up again when there is different FIELD decls.
itemfunptrD.21695.__pfnD.21700 ={v} itemfunD.21696;
memfunD.24341 ={v} itemfunptrD.21695;
memfun$__pfnD.24346_4 = memfunD.24341.__pfnD.21692;
You can see how the two different field decls are allocated. I don't know if I
want to mark this a front bug or a middle one.

[Bug boehm-gc/37017] New: [4.2 regression] Using --enable-threads=solaris breaks near end of build in boehm-gc configury
When configuring with --enable-threads=solaris the build runs for hours and then breaks after the libgfortran finished when configuring boehm-gc . It would be nice if the main configure script caught this instead of the build failing just as it was about to finish. I am building gcc-4.2.3 release from: ftp://ftp.gnu.org/gnu/gcc/gcc-4.2.3/gcc-4.2.3.tar.bz2 A similar complaint is made here: Fortran and objc Hans Boehm GC build issues -- sparcv9 libs http://gcc.gnu.org/ml/gcc-help/2006-09/msg00108.html A claim that configuring with --enable-threads=solaris was fixed is made here: [4.1/4.2 regression] libstdc++ cannot be build with Solaris threads http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28247 If you are going to build this you need to fixup the Makefiles to get "--with-gmp=/opt/gnu/gmp-4.2.2 --with-mpfr=/opt/gnu/mpfr-2.3.1" to work, yet "--with-libiconv-prefix=/opt/csw" works fine. # gcc/xgcc -v Using built-in specs.

--- Comment #2 from rob1weld at aol dot com 2008-08-04 01:28 ---
> Is there a reason why you are not using just --enable-threads=pthreads?
A few reasons.
1. I test _all_ of gcc's configure options, submit bug reports and email test
results - "--enable-threads=solaris" is a valid choice.
2. There are more features on this Operating System. With Solaris it enables
Solaris threads _and_ pthreads simultaneously.

[Bug libgcj/37019] New: [4.2 Regression] Inconsistent gcc-4.2.3/libjava/configure uses "grep" and "egrep" and "grep -E" and "$EGGREP" but not ggrep -- sed also is trouble
The gcc-4.2.3/libjava/configure uses "grep" and "egrep" and "grep -E" and "$EGGREP" (but not "ggrep") in a non-portable and inconsistent manner. Examples: 1. Lines 5224, 5254, 5295, 5298, etc... use "egrep" but "EGREP" is not tested for (to decide if we will use "grep -E" or "egrep") until line 7315 and not set until line 7322. Correct usage would be to check if we need to use "ggrep" since on Solaris "grep" is NOT the GNU grep, instead "ggrep" is the GNU grep. A few simple commands in Solaris's "grep" _are_ compatable with GNU's "grep" but most commands are not. Solaris also has "egrep" and "fgrep" but those are also both Non-GNU programs. To use "egrep" or "fgrep" (in Solaris) you must use "ggrep -E" or "ggrep -F". --- The other problem is that Solaris (I have the newest version) does not have a GNU sed program. Worse news. It _does_ have a "sed" program, but there is no command to obtain a version number. Looking at the "man sed" command says that the man page is dated "23 Jul 1998". In a "normal" installation of Solaris there is no "gsed" command. The GNU "sed" command can be tested by running "sed --version" and it will reply "GNU sed version x.y.z". The Solaris "sed" command has no means to check it's version (that I am aware of -- you might ggrep the binary ;) ). If someone wants a "gsed" command for Solaris they must either compile "sed" themselves or type this (see this URL: http://www.blastwave.org/howto.html): # pkgadd -d http://www.blastwave.org/pkg_get.pkg # /opt/csw/bin/pkg-get -U # /opt/csw/bin/pkg-get -i wget # /opt/csw/bin/pkg-get -i gsed That provides a "GNU sed" as "/opt/csw/bin/gsed". It is version 4.1.4 Elsewhere in gcc I have noticed that other configure scripts do not have this problem, they do check for the "g"-prefixed commands. The (correct) configury uses tests to set environment variables that are used for the program's name throughout the rest of the script. -- Summary: [4.2 Regression] Inconsistent gcc- 4.2.3/libjava/configure uses "grep" and "egrep" and "grep -E" and "$EGGREP" but not ggrep -- sed also is trouble Product: gcc Version: 4.2.3 Status: UNCONFIRMED Severity: major Priority: P3 Component: libgcj AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: rob1weld at aol dot com GCC build triplet: i386-pc-solaris2.11 GCC host triplet: i386-pc-solaris2.11 GCC target triplet: i386-pc-solaris2.11 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37019

while compiling getting error as : error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘extern’
Hi, I am using gcc (GCC) 4.2.1 (SUSE Linux). SUSE 10.3 While compiling a .c file I get following error Configuration.h:70: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘extern’ can anybody tell me ways to sort out such problems.
