the new test FAILs on Solaris/x86, both 32 and 64-bit:
FAIL: gcc.dg/torture/builtin-fp-int-inexact-c2x.c -O0 execution test
FAIL: gcc.dg/torture/builtin-fp-int-inexact-c2x.c -O1 execution test
FAIL: gcc.dg/torture/builtin-fp-int-inexact-c2x.c -O2 execution test
FAIL: gcc.dg/torture/builtin-fp-int-inexact-c2x.c -O2 -flto execution test
FAIL: gcc.dg/torture/builtin-fp-int-inexact-c2x.c -O2 -flto
-flto-partition=none execution test
FAIL: gcc.dg/torture/builtin-fp-int-inexact-c2x.c -O3 -g execution test
The test aborts. This happens because dg-add-options c99_runtime
appends -std=c99 to the options, yielding -std=c2x -std=c99. If I
manually omit the -std=c99, the test PASSes. I'm uncertain yet how to
handle this. Maybe prepending -std=c99 is an option, but that may well
break other tests...
