[patch] removing aged ifdef 0 from boehm-gc/os_dep.c
This is my first effort at contributing to gcc, so I thought I would try
with some of the easy stuff listed here:
https://gcc.gnu.org/projects/beginner.html
Attached is a patch removing a block which has been #if 0'd out since
2006. I tested the build afterward.
I look forward to your feedback.

[PATCH] pr 65702 - error out for invalid register asms earlier
From: Trevor Saunders
Hi,
$subject. To avoid regressions I kept the checks when generating rtl, but I
believe its impossible for those to trigger now and we can remove the checks.
bootstrapped + regtested on x86_64-linux-gnu, ok?

[PATCH] obsolete the deprecated rtems targets
From: Trevor Saunders
hi,
Joel said in http://gcc.gnu.org/ml/gcc/2016-01/msg00016.html we should drop
support for these targets because rtems has stopped supporting them, so this
marks them as obsolete and we can remove them in gcc 7.
tested building for {avr,h8300,m32r}-rtems without --enable-obsolete fails, and
make all-gcc for i686-linux-gnu succeeds. ok?

[PATCH] add basic .gitattributes files to notice whitespace issues
From: Trevor Saunders
Hi,
We can tell git to highlight whitespace errors in diffs, and if you enable the
default pre-commit hook git won't allow you to make a commit with a whitespace
error violating the rules you told it about. These files as are could be
improved some, they don't enforce whitespace rules on testsuite .exp files, and
I'm not sure if we want to allow whitespace errors in testsuites for libraries,
but I'd like to see if other people can suggest other improvements.

[PATCH] teach mklog to look in the current directory for ChangeLog files
From: Trevor Saunders
when run in repos other than gcc mklog fails to find ChangeLog files
because it looks for $0/../$dir/ChangeLog, but of course if the diff is
for a project other than gcc that might not exist. It should be fine to
also look for $cwd/$dir/ChangeLog, and use that if we find it. This
means that for example in binutils-gdb.git you can do git commit,
and then in your editor read git diff HEAD~ | mklog - to generate a
template ChangeLog for that commit.
I've tested mklog still generates the write ChangeLog entries for gcc and
binutils repos, ok?

[PATCH 0/5] remove tm.h from encoding.c
From: Trevor Saunders
Hi,
Its not the nicest code in the world, and there's definitely room for cleanups,
however it seems like an improvement. After this series the only usage of tm.h
in libobjc is thr.c which only uses tm.h so it can include gthr.h which uses
SUPPORTS_WEAK and possibly other target macros.
bootstrapped + regtested patches individually on x86_64-linux-gnu, also tested
the
series as a whole doesn't regress check-objc on ppc64{,le}-linux-gnu and AIX,
ok?
Trev
Trevor Saunders (4):
remove usage of ROUND_TYPE_SIZE from encoding.c
stop using ROUND_TYPE_ALIGN in libobjc/
remove usage of BIGGEST_FIELD_ALIGNMENT in encoding.c
remove usage of ADJUST_FIELD_ALIGN in encoding.c

[PATCH 3/5] stop using ROUND_TYPE_ALIGN in libobjc/
From: Trevor Saunders
Given the layering violation that using ROUND_TYPE_ALIGN in target libs
is, and the hacks needed to make it work just coppying the relevant code
into encoding.c seems to make sense as an incremental improvement. The
epiphany version of this macro called a function that doesn't exist in
target libs, so libobjc must not build on that target and not coppying
that macro definition doesn't make anything worse. We already
explicitly prefered the default version to the macro for sparc so we
don't need to copy that version either. On ppc linux64 and freebsd64
after constant folding values of other target macros used for libobjc
the macro turned out to be the same as the default version so we can
just use the default for them. Which means the only version of the
macro we actually need to copy are for ppc-darwin and AIX.

[PATCH 4/5] remove usage of BIGGEST_FIELD_ALIGNMENT in encoding.c
From: Trevor Saunders Similar to ROUND_TYPE_ALIGN it seems to make sense to copy the information in the target macros to libobjc as an incremental step. Its worth noting a large portion of the definitions of this macro only exist to work around ADJUST_FIELD_ALIGN being used in target libs, so once all target macros are gone from target libs we should be able to remove most of the definitions of BIGGEST_FIELD_ALIGNMENT in gcc/, at which point there won't be a significant amount of dupplication. libobjc/ChangeLog: 2015-10-30 Trevor Saunders PR libobjc/24775 * encoding.c (objc_layout_structure_next_member): Remove usage of BIGGEST_FIELD_ALIGNMENT. --- libobjc/encoding.c | 14 -- 1 file changed, 12 insertions(+), 2 deletions(-) diff --git a/libobjc/encoding.c b/libobjc/encoding.c index 867372d..7438d64 100644 --- a/libobjc/encoding.c +++ b/libobjc/encoding.c @@ -1158,8 +1158,18 @@ objc_layout_structure_next_member (struct objc_struct_layout *layout) } /* The following won't work for vectors. */ -#ifdef BIGGEST_FIELD_ALIGNMENT - desired_align = MIN (desired_align, BIGGEST_FIELD_ALIGNMENT); +#if defined __x86_64__ || defined __i386__ +#if defined __CYGWIN__ || defined __MINGW32__ + desired_align = MIN (desired_align, 64); +#elif defined __x86_64__ + desired_align = MIN (desired_align, 128); +#else + desired_align = MIN (desired_align, 32); +#endif +#elif defined __tilepro__ || defined __frv__ || defined __arm__ + desired_align = MIN (desired_align, 64); +#elif defined __tilegx__ + desired_align = MIN (desired_align, 128); #endif #ifdef ADJUST_FIELD_ALIGN desired_align = ADJUST_FIELD_ALIGN (type, desired_align); -- 2.6.2

[PATCH 03/12] remove conditional compilation of sdb debug info
From: Trevor Saunders
We need to include gsyms.h before tm.h because some targets (rl78 iirc) define
macros that conflict with identifiers in gsyms.h. This means sdbout.c won't
produce correct output for those targets, but it previously couldn't either
because it wasn't compiled at all.
gcc/ChangeLog:
2015-11-09 Trevor Saunders
* defaults.h: New definition of SDB_DEBUGGING_INFO.
* doc/tm.texi: Regenerate.
* doc/tm.texi.in: Adjust.
* final.c (rest_of_clean_state): Remove check if
SDB_DEBUGGING_INFO is defined.
* function.c (number_blocks): Likewise.
* output.h: Likewise.
* sdbout.c: Likewise.
* toplev.c (process_options): Likewise.

[PATCH] PR 68366 - include emit-rtl.h in sdbout.c
From: Trevor Saunders Some of the pa target macros rely on macros in emit-rtl.h and sdbout.c uses some of those macros, which means that sdbout.c needs to include emit-rtl.h. this seems obvious, bootstrapped on x86_64-linux-gnu, and checked that a cross to hppa-linux now builds so committing to trunk.

[PATCH 1/2] destroy values as well as keys when removing them from hash maps

This fixes several leaks where a hash_map user expected deleting the map to
destruct the value part of entries as well as the key. A couple of these bugs
have already been fixed, but there are more of them for example some of the
sanitizer code, and tree-if-conv.c). The expectation that hash_map should
destruct values seems to be pretty obviously correct, so we should fix that to
fix the existing bugs and prevent future ones (I also seem to remember that
working at some point, but could be incorrect).
I checked all the existing hash_map users and couldn't find any value types
other than auto_vec with destructors, so its the only one with a non trivial
destructor. So the only effected case auto_vec is fixed by this patch and no
expectations are broken.
bootstrapped + regtested on x86_64-linux-gnu, ok?

[PATCH] remove need for store_values_directly
From: Trevor Saunders
Hi,
Last stage 1 I introduced a second form of hash_table that stored elements of
value_type in addition to the old form that stored elements of type value_type
*. That lead to a fair bit of code dupplication in hash_table, but it
simplified the transition by allowing it to take place one hash table at a
time. Now I'm switching the rest of the hash_table users to use the new setup,
and removing supporot for the old one.
this was bootstrapped and regtested on x86_64-unknown-linux-gnu, and I ran make
all-gcc for the following crosses to check the hash tables they use were
correctly converted
arm-linux-androideabi
i686-apple-darwin
i686-solaris2.11
i686-w64-mingw32
ia64-linux
mips64-linux
nvptx-elf
ppc64-linux
Is this ok?

[PATCH 00/12] Reduce conditional compilation
From: Trevor Saunders Hi, This is a first round of patches to reduce the amount of code with in #if / #ifdef. This makes it incrementally easier to not break configs other than the one being built, and moves things slightly closer to using target hooks for everything. each commit bootstrapped and regtested on x86_64-linux-gnu without regression, and whole patch set run through config-list.mk without issue, ok? Trevor Saunders (12): add default definition of EH_RETURN_DATA_REGNO remove some ifdef HAVE_cc0 more HAVE_cc0 always define HAVE_cc0 make some HAVE_cc0 code always compiled provide default for RETURN_ADDR_OFFSET provide default for MASK_RETURN_ADDR reduce conditional compilation for HARD_FRAME_POINTER_IS_FRAME_POINTER remove #if for PIC_OFFSET_TABLE_REGNUM remove more ifdefs for HAVE_cc0 provide default for INSN_SETS_ARE_DELAYED add default for INSN_REFERENCES_ARE_DELAYED gcc/alias.c | 7 ++--- gcc/builtins.c| 2 -- gcc/caller-save.c | 4 +-- gcc/cfgcleanup.c | 26 +--- gcc/cfgrtl.c | 12 ++-- gcc/combine.c | 84 ++- gcc/conditions.h | 6 gcc/cprop.c | 4 +-- gcc/cse.c | 22 +- gcc/defaults.h| 23 ++ gcc/df-problems.c | 9 ++ gcc/df-scan.c | 46 +++- gcc/emit-rtl.c| 8 ++--- gcc/except.c | 26 ++-- gcc/final.c | 43 -- gcc/function.c| 5 ++- gcc/gcse.c| 24 --- gcc/genconfig.c | 1 + gcc/haifa-sched.c | 5 +-- gcc/ira-lives.c | 2 -- gcc/ira.c | 33 +--- gcc/jump.c| 3 -- gcc/loop-invariant.c | 4 +-- gcc/lra-constraints.c | 6 ++-- gcc/lra-lives.c | 2 -- gcc/optabs.c | 2 +- gcc/postreload.c | 4 +-- gcc/recog.c | 2 -- gcc/recog.h | 2 -- gcc/reginfo.c | 5 ++- gcc/regrename.c | 5 ++- gcc/reload.c | 12 +++- gcc/reload1.c | 10 +++--- gcc/reorg.c | 68 ++--- gcc/resource.c| 15 +++-- gcc/rtlanal.c | 2 -- gcc/sched-deps.c | 5 +-- gcc/sched-rgn.c | 4 +-- gcc/simplify-rtx.c| 5 ++- 39 files changed, 199 insertions(+), 349 deletions(-) -- 2.3.0.80.g18d0fec.dirty

[PATCH 0/8] remove more conditional compilation
From: Trevor Saunders Hi, Here's another series to remove some conditional compilation. each patch was bootstrapped and regtested on x86_64-linux-gnu, and the series was run through config-list.mk. I think this all falls within Jeff's preapproval so I'll commit it tomorrow (today actually) night if nobody objects.
