Hi!
The following testcase shows -fcompare-debug bugs in ifcvt_local_dce,
where the decisions what statements are needed is based also on debug stmt
operands, which is wrong.
So, this patch makes sure to never add debug stmt to the worklist, or never
add an assign to worklist just because it is

Hi!
The following testcase FAILs with -fcompare-debug. The problem is that
the C++ FE initially uses IF_STMTs, tcc_statement which default to
TREE_SIDE_EFFECTS set, but later on is genericized into COND_EXPRs,
tcc_expression which default to TREE_SIDE_EFFECTS ored from all 3 operands.

Hi!
The following testcase ICEs, because these expanders will happily create
a SImode 0x8000 CONST_INT, which is not valid RTL, as CONST_INTs need to
be sign extended from the mode precision to full HWI.
Fixed thusly, bootstrapped/regtested on armv7hl-linux-gnueabi, ok for trunk?

All right, there's update endianess detection that should be robust
enough.
I've tested that on x86_64-linux-gnu and sparc64-linux.
Ready for master?
Thanks,

Some tests require double-precision support, but the existing
arm_fp_ok effective-target only checks if hardware floating-point is
available, not what level. So this patch adds a new arm_fp_dp_ok
effective-target to check that double-precision is supported.

Parts of the cmp-2.c test rely on double-precision support, making the
test fail on targets where the FPU supports single-precision only.
Split the test into single-precision (cmp-2.c) and double-precision
tests (cmp-3.c).

I was looking into this yesterday but I ran into some issues.
The first is that blindly converting each output to in+out breaks
cases where an input already overlaps with an output:
asm ("..." : "=r" (out) : "0" (in));
This could be worked around by scanning the input list and only

rs6000: Update bswap64-4 test to reflect actual results
Hi,
Update existing testcase powerpc/bswap64-4.c to
reflect that we generate ldbrx and stdbrx instructions
for newer cpu targets. This is in contrast to the
pair of lwbrx and stwbrx instructions that are
generated with older cpu targets.
Thanks to Frank Ch. Eigler for the updated link.
Pushed.
