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
Rafael Espindola	ac95264d62	Don't depend on dynamic relocatinos in ro sections. ... Currently we don't check when creating relative relocations if the section is read only or not. I am about to fix that, so first update the patches that depend on the current behavior. llvm-svn: 268542	2016-05-04 20:25:19 +00:00
George Rimar	786e866fea	[ELF] - -pie/--pic-executable option implemented ... -pie --pic-executable Create a position independent executable. This is currently only supported on ELF platforms. Position independent executables are similar to shared libraries in that they are relocated by the dynamic linker to the virtual address the OS chooses for them (which can vary between invocations). Like normal dynamically linked executables they can be executed and symbols defined in the executable cannot be overridden by shared libraries.
