Jens Remus 76f05e1dfb readelf/objdump: Dump SFrame CFA fixed FP and RA offsets ... The SFrame format allows architectures to specify fixed offsets from the CFA, if any, from which the frame pointer (FP) and/or return address (RA) may be recovered. These offsets are stored in the SFrame header. For instance the SFrame generation in the assembler for x86 AMD64 specifies a fixed offset from the CFA, from which the return address (RA) may be recovered. When dumping the SFrame header, for instance in readelf/objdump with option --sframe, do also dump the specified fixed offsets from the CFA, if any, from which the frame pointer (FP) and return address (RA) may be recovered. Update the common SFrame test case verification patterns to allow for the optional dumping of the CFA fixed FP/RA offsets. Update the x86- specific SFrame and SCFI test case verification patterns to require a CFA fixed RA offset of -8. libsframe/ * sframe-dump.c: Dump CFA fixed FP and RA offsets. gas/testsuite/ * gas/cfi-sframe/cfi-sframe-common-1.d: Test for optional fixed FP and RA offsets. * gas/cfi-sframe/cfi-sframe-common-2.d: Likewise. * gas/cfi-sframe/cfi-sframe-common-3.d: Likewise. * gas/cfi-sframe/cfi-sframe-common-4.d: Likewise. * gas/cfi-sframe/cfi-sframe-common-5.d: Likewise. * gas/cfi-sframe/cfi-sframe-common-6.d: Likewise. * gas/cfi-sframe/cfi-sframe-common-7.d: Likewise. * gas/cfi-sframe/cfi-sframe-common-8.d: Likewise. * gas/cfi-sframe/cfi-sframe-x86_64-1.d: Test for fixed RA offset. * gas/cfi-sframe/common-empty-1.d: Test for optional fixed FP and RA offsets. * gas/cfi-sframe/common-empty-2.d: Likewise. * gas/cfi-sframe/common-empty-3.d: Likewise. * gas/scfi/x86_64/scfi-cfi-sections-1.d: Test for SFrame fixed RA offset. * gas/scfi/x86_64/scfi-dyn-stack-1.d: Likewise. ld/testsuite/ * ld-x86-64/sframe-plt-1.d: Test for SFrame fixed RA offset. * ld-x86-64/sframe-simple-1.d: Likewise.
