--- Comment #10 from Rainer Orth <ro at gcc dot gnu.org> ---
The new test currently FAILs on Solaris/SPARC with the native as:
FAIL: gcc.dg/pr115066.c scan-assembler \\\\.byte\\\\t0xb\\\\t# Define macro
strx
The relevant snippet of pr115066.s is
.section ".debug_macro.dwo",#exclude,#progbits
.LLdebug_macro0:
.uahalf 0x4 ! DWARF macro version number
.byte 0x2 ! Flags: 32-bit, lineptr present
.uaword .LLskeleton_debug_line0
.byte 0x1 ! Define macro
while when using gas, I have
.section .debug_macro.dwo,"e",@progbits
.LLdebug_macro0:
.uahalf 0x4 ! DWARF macro version number
.byte 0x2 ! Flags: 32-bit, lineptr present
.uaword .LLskeleton_debug_line0
.byte 0xb ! Define macro strx
AFAICS from dwarf2out.cc (output_macinfo_op), the requirements for using
DW_MACRO_define_strx are (among others)
!DWARF2_INDIRECT_STRING_SUPPORT_MISSING_ON_TARGET && SECTION_MERGE.
However, with the native assembler, SHF_MERGE doesn't work (as emits something
ld cannot link).
I wonder how best to handle this: just skip the test on sparc*-sun-solaris2* &&
!gas? Theoretically, there could be other targets with similar issues.
