You can extend this to cover the other cases you mention.

[Bug rtl-optimization/63259] Detecting byteswap sequence
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63259
--- Comment #10 from thopre01 at gcc dot gnu.org ---
(In reply to Oleg Endo from comment #9)
(In reply to thopre01 from comment #7)
Strange, could you show the output of -fdump-tree-bswap?
Not so strange at all.
What is strange is that it should detect such bswap pattern.
After looking at the RTL dumps, I've noticed that
the swap.b insn is generated by the combine pass. I've got a few combine
patterns for matching byte swaps on SH. The pattern for swap.b doesn't
combine well with other ops around/on it. -fdump-tree-bswap says:
;; Function test_08 (test_08, funcdef_no=1, decl_uid=1333, cgraph_uid=1,
symbol_order=1)
test_08 (short unsigned int a, short unsigned int b)
{
short unsigned int _2;
signed short _3;
int _4;
int _5;
signed short _6;
signed short _7;
short unsigned int _8;
short unsigned int _10;
bb 2:
_2 = a_1(D) 8;
_3 = (signed short) _2;
_4 = (int) a_1(D);
_5 = _4 8;
_6 = (signed short) _5;
_7 = _3 | _6;
_8 = (short unsigned int) _7;
_10 = _8 + b_9(D);
return _10;
}
I have the same gimple and for me the bswap is correctly detected. Can you
break at find_bswap_or_nop just after calling find_bswap_or_nop_1 on the if
(!source_stmt) and show me the output of p/x n-n ?
Byte swapping of signed short types seems to be not working:
short test_func_111 (short a, short b, short c)
{
return (((a 0xFF00) 8) | ((a 0xFF) 8));
}

That's expected. Think about what happens if a = 0x8001. Doing a right shift
by 8 bit would give 0xFF80 (due to the most significant bit being 1). The
right part of the bitwise OR would give 0x0100 as expected and the result
would be 0xFF80, so not a byte swap. It would work with an int though as the
highest bit would then be 0, or with unsigned short as a right shift would
introduce 0 in the most significant bits.
As Andreas mentioned, 'a' is promoted to int, so this should be a byte swap.
Indeed, my mistake. Ok I tested a bit and found that the problem is the depth
at which it's looking. Try to recompile tree-ssa-math-opts.c after increasing
the limit number in find_bswap_or_nop. Right now the limit will evaluate to 4
and the gimple I have has a depth of 5.
[Bug tree-optimization/64308] Missed optimization: 64-bit divide used when 32-bit divide would work
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64308 --- Comment #2 from Marc Glisse glisse at gcc dot gnu.org --- You would need symbolic ranges, b and ret are in [0,m-1]. And then you are using that very specific x86 instruction that divides 64 bits by 32 bits but only works if the result fits in 32 bits. It works here because (m-1)*(m-1)/mm is small enough, but that's very hard for the compiler to prove, and I don't know of another architecture with a similar instruction. (Related: PR58897, PR53100)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64313 Richard Biener rguenth at gcc dot gnu.org changed: What|Removed |Added CC||jsm28 at gcc dot gnu.org --- Comment #2 from Richard Biener rguenth at gcc dot gnu.org --- For aarch64-elf ordinary builtins declared as DEF_LIB_BUILTIN are implicitely available but for example expf is not as the target computes targetm.libc_has_function (function_c99_misc) as false. This is because of config/elfos.h:#undef TARGET_LIBC_HAS_FUNCTION config/elfos.h:#define TARGET_LIBC_HAS_FUNCTION no_c99_libc_has_function One solution is to properly guard the testcase with c99_runtime (even GNU runtime, as it uses exp10/log10/pow10). But it expects all tests to be folded away which means that builtins need to be recognized (which they are because they match their prototype - sth that is not enough according to Joseph). IMHO even if system headers declare such prototype we can't be sure they are really the correct function (system headers include non-C-library runtime headers). To be sure we'd need to know the names are really reserved which for example for exp10 is if _GNU_SOURCE is defined at the point of prototyping exp10. Not sure if what libcpp provides for this is convenient (there are some related callbacks to track what is defined / undefined), but whatever we do it should also work for -save-temps which means we need to make sure to emit the #defines to the preprocessed source as well and _not_ use -fpreprocessed(?). The pragmatic solution is to make builtins implicitely available once they are seen in the instruction stream, for example during gimplification. A more complex solution is to turn genmatch upside-down and make it clever, similar to how fold_builtin_logarithm gets around this - re-use the decl we get in the matching IL. Note that this isn't easily possible with low overhead (well, maybe making code_helper a bit heavier weight and pass tree_code or builtin decl around). I'm leaning towards either reverting the single builtin patch for GCC 5 or implementing the pragmatic solution.

[Bug libstdc++/64315] New: num_put misbehaves if the C library doesn't support floats
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64315 Bug ID: 64315 Summary: num_put misbehaves if the C library doesn't support floats Product: gcc Version: 5.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: ville.voutilainen at gmail dot com In num_put::_M_insert_float, __convert_from_v can fail, leading into a __widen being called with a negative size. This may happen with a C library that has a sprintf that refuses to support floats and returns -1 when a float is used with it.

Yes, this commit (authored by myself) is definitely the culprit here. The nontriviality in the given test case is that we have to deal with a generic type-bound call, which is being resolved to a non-overridable type-bound call. 'resolve_typebound_generic_call' should probably communicate to its caller that the specific procedure it found is not overridable.

(In reply to janus from comment #3)
'resolve_typebound_generic_call' should probably communicate to its caller
that the specific procedure it found is not overridable.
It turns out that resolve_typebound_generic_call actually does update this
information in the gfc_expr, but then resolve_typebound_call needs to pass it
outside, before it transforms the whole thing into an EXEC_CALL.
Here is a draft patch which does this (making the ICE disappear):

[Bug target/64149] -mno-lra bitrots, suggest to remove for GCC 5
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64149 --- Comment #2 from Richard Earnshaw rearnsha at gcc dot gnu.org --- Sounds sensible to me. We switched to LRA quite late in gcc-4.9, so keeping a way to switch back in case of problems was pragmatic. But we've been running with the new code now for a year and not encountered any major issues that couldn't be fixed pretty quickly.
