Peter Collingbourne	628ec9f193	ELF: Place relro sections after non-relro sections in r/w segment. This is in preparation for my next change, which will introduce a relro nobits section. That requires that relro sections appear at the end of the progbits part of the r/w segment so that the relro nobits section can appear contiguously. Because of the amount of churn required in the test suite, I'm making this change separately. llvm-svn: 291523	2017-01-10 01:21:30 +00:00
Peter Smith	d92099991b	[ELF] Add R_ARM_RELATIVE to relocations that can be applied to GotSection When compiling -fpie and linking with the --pie option the R_ARM_GOTBREL relocation to D is resolved by writing the value of D into the .got slot and emitting an R_ARM_RELATIVE relocation for it. This changes adds the R_ARM_RELATIVE relocation to the switch in relocateOne() so we can process the GotSection relocation to write the value of the variable as well as emitting the dynamic relocation.

ELF: Place relro sections after non-relro sections in r/w segment.

This is in preparation for my next change, which will introduce a relro
nobits section. That requires that relro sections appear at the end of the
progbits part of the r/w segment so that the relro nobits section can appear
contiguously.

Because of the amount of churn required in the test suite, I'm making this
change separately.

[ELF] Add R_ARM_RELATIVE to relocations that can be applied to GotSection

When compiling -fpie and linking with the --pie option the R_ARM_GOTBREL
relocation to D is resolved by writing the value of D into the .got slot
and emitting an R_ARM_RELATIVE relocation for it.
    
This changes adds the R_ARM_RELATIVE relocation to the switch in
relocateOne() so we can process the GotSection relocation to write the
value of the variable as well as emitting the dynamic relocation.
