gas: sframe: guard block with support_sframe_p
SFrame is generated for ELF targets only. Guard the block with
support_sframe_p like others for consistency.
Also, in a later commit, we would like to do a:
elf_section_type (sframe_seg) = SHT_GNU_SFRAME;
This cannot be done for non-ELF targets, hence the need to guard with
some pre-processor conditional to enable it for only OBJ_ELF. Guarding
with support_sframe_p works for now, because those targets that support
SFrame define support_sframe_p:
- x86_64 and aarch64 define support_sframe_p when OBJ_ELF is defined
- s390x has no non-LEF target.
We continue to issue an error on targets where SFrame is not supported:
.sframe not supported for target
gas/
* dw2gencfi.c (cfi_finish): Guard with support_sframe_p.
(support_sframe_p): Remove stub to define to false for backends
not supporting SFrame.
