sframe: Add tests for PR ld/32769
Add simple tests that verify the behavior of garbage collection of
SFrame sections during linking.
x86_64-specific tests:
- sframe-gc-sections-1.d checks that none of the functions get
discarded with --gc-sections
- sframe-gc-sections-2a.d checks the behavior of --gc-sections with two
distinct .text.* sections (similar to -ffunction-sections compiler
option)
- sframe-gc-sections-2b.d checks the same behaviour as
sframe-gc-sections-2a.d, but with a linker script that discards
.eh_frame sections. This testcase is keep it ensured that the two
section's GC behaviours are not unnecessarily inter-twined.
All targets supporting sframe tests:
- pr32769.rd simple linking test in presence of --gc-sections
option.
- pr32769-2.d checks the behavior of --gc-sections with two .text.*
sections, one section is discarded
- pr32769-2r.d Like the above, but using -r option when linking and
checking for the relocations.
- pr32769-3.d checks the behavior of --gc-sections with multiple
sections, none is drop.
