From: Stefan Schulze Frielinghaus <[email protected]>
Initially asm-hard-reg-2.c was intended to be considered only on 64-bit
x86. Commit r16-3110 restricted this to { ! ia32 } which still includes
the test for i?86 ILP32 for which we get "warning: unsupported size for
integer register". Since the test is about integer type long long
and GPRs, restrict this to lp64.
Test asm-hard-reg-5.c fails on powerpc64-*-* since option -maltivec is
missing.
Test asm-hard-reg-6.c is failing for ARM Thumb-2 e.g. if options -mthumb
-march=armv8.1-m.main+mve.fp+fp.dp -mtune=cortex-m55 -mfloat-abi=hard
-mfpu=auto are used. In that case GPR pairs must be in even/odd pairs in
contrast to Thumb-1. Fix this by changing GPR3 to r4.
gcc/testsuite/ChangeLog:
* gcc.dg/asm-hard-reg-2.c: Restrict to x86 && lp64.
* gcc.dg/asm-hard-reg-5.c: Ensure option -maltivec is specified
for powerpc64-*-*. For x86, copy the target selector from
dg-compile for the scan-assembler directive.
* gcc.dg/asm-hard-reg-6.c: Use an even/odd register pair for ARM
Thumb-2.

Tested via cross compilers for
- arm-unknown-linux-gnueabi
- i686-ubuntu16.04-linux-gnu
- powerpc64le-unknown-linux-gnu
- powerpc64-unknown-linux-gnu
- powerpc-unknown-linux-gnu
- x86_64-unknown-linux-gnu
I guess this commit falls under the "obvious rule", though, I will give
maintainers some time to chime in before pushing this sometime next
week.
I hope to get a clean asm-hard-reg-*.c test suite some time. Sorry for
all the noise; there are quite some configurations which were new to me.
