[patch committed FT32] use setup_incoming_varargs

The FT32 target now uses SETUP_INCOMING_VARARGS to handle varargs. This saves 24 byte per stack frame, because the caller no longer needs to allocate space on the stack for r0-r5 in the event of a varargs caller. * config/ft32/ft32.c (ft32_setup_incoming_varargs,

[PATCH, i386]: Fix PR 71389, ICE on trunk gcc on ivybridge target (df_refs_verify)

Hello! As explained in the PR [1] Comment #4, this is a target problem with invalid RTL sharing. Invalid sharing is created by the misaligned expansion code in i386.c, when subregs are involved. vec_extract_hi_v32qi pattern is generated in loop2_invariant pass when misaligned V8SI move is

Hi, both loop-ch and loop-ivcanon want to trottle down the heuristics on paths containing call. Testing for presence of GIMPLE_CALL is wrong for internal call and cheap builtins that are expanded inline. Bootstrapped/regtested x86_64-linux, OK? Honza * gimple.c: Include builtins.h.

[v3 PATCH] Support allocators in tuples of zero size.

All in all this is a bit inane, but the spec requires a zero-sized tuple to provide allocator overloads for constructors, even though they do absolutely nothing (they completely ignore the allocator). Presumably these are also useful for some metaprogrammers I haven't heard of. This takes us one

Avoid mutiple predictions out of loop predictors

Hi, this patch makes loop predictors to run smoother on exists which quits multiple loops. Currently we will place multiple predictors on each such exit that does not really work as expected: PRED_LOOP_ITERATIONS predictors does not really expect the exit to be inside of internal loop and will

Silence bogus mismatched profile messages

Hi, calls to functions that will not return cause profile to look locally incorrect. (because the sum of outgoing frequencies does not match the BB frequency). Do not report that. This makes it easier to analyze C++ sources. On tramp3d we now have about 20 mismatches caused by loop unroling about

[PING] [PATCH] Make basic asm implicitly clobber memory

Ping... I think we all agreed on the general direction of this patch. The patch is basically unchanged from previous version, except one line in doc/extend.texi has been updated. So I would like to ask if it is OK for trunk. Thanks Bernd.gcc/ 2016-05-05 Bernd Edlinger

[PR71408] - Fix wrong code at -Os and above

Hi All, For the testcase in PR71408 zero_one_operation seems still broken. In handling NEGATE_EXPR, as part of undistribute_ops_list, in zero_one_operation, we are doing propagate_op_to_single_use (op, stmt, def); This results in: - _14 = _5 * _12; _15 = (int) _11; _16 = ~_15; _17
