The test fails on arm-eabi when testing with the following settings: -mlittle-endian -mfloat-abi=hard -mcpu=cortex-a9 -mfpu=vfpv3
It only fails in the following torture option set: -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions
Isn't that combination excluded by /* { dg-skip-if "" { *-*-* } { "-ftracer" } { "" } } */ at the beginning of the testcase?
It also fails on numerous other 32-bit targets, but it depends on how the memcpy-like loop gets vectorized and unrolled.
I hope we can live with the XPASSes.
I suppose so.
That being said, I see this test PASS on all arm-*-eabi versions I am testing: -marm/-march=armv7-a/-mfpu=auto/-mfloat-abi=soft -marm/-march=armv7-a/-mfpu=vfpv3-d16/-mfloat-abi=softfp -mthumb/-march=armv6s-m/-mtune=cortex-m0/-mfloat-abi=soft/-mfpu=autp -mthumb/-march=armv8-m.base/-mtune=cortex-m23/-mfloat-abi=soft/-mfpu=auto -mthumb/-march=armv7-m/-mtune=cortex-m3/-mfloat-abi=softfp -mthumb/-march=armv8-m.main+dsp+fp/-mtune=cortex-m33/-mfloat-abi=hard/-mfpu=auto -mthumb/-march=armv7e-m+fp/-mtune=cortex-m4/-mfloat-abi=hard/-mfpu=auto -mthumb/-march=armv8.1-m.main+mve.fp+fp.dp/-mtune=cortex-m55/-mfloat-abi=hard/-mfpu=auto -mthumb/-march=armv7e-m+fp.dp/-mtune=cortex-m7/-mfloat-abi=hard/-mfpu=auto -mthumb/-march=armv7-a/-mfpu=vfpv3-d16/-mfloat-abi=softfp -mthumb/-march=armv8-a+simd/-mfpu=auto/-mfloat-abi=hard
I see one failure: FAIL: gcc.dg/torture/pr113026-1.c -O3 -g (test for bogus messages, line 12)
on armeb-none-eabi with -marm/-march=armv7-a/-mfpu=neon/-mfloat-abi=hard
on arm-linux-gnueabihf and armeb-linux-gnueabihf the tests PASS.
In summary on arm-*-eabi for RUNTESTFLAGS=dg-torture.exp=pr113026-1.c with your patch I have now 7 PASS + 7 XPASS + 1 UNSUPPORTED while I had 14 PASS + 1 UNSUPPORTED without your patch.
Thanks,
