[PATCH] [x86_64] Don't truncate PC-relative relocations in ELF EH frames to 32 bits

[pitrou at free.fr]

Hello,

I see this issue has generated several changesets. The latest one seems to be http://reviews.llvm.org/rL222897, where only the Large code model avoids truncation. Am I correct in understanding that the JITDefault code model still generates truncations?

At Numba we've maintained a more encompassing patch and it allowed us to eliminate occasional crashes on x86-64 (we use the JITDefault code model):

Also there seem (?) to be sibling issues:
