78e3168c97 JITLink/ELF_i386.cpp: Fix a warning in D141746. [-Wswitch] 2023-01-14 15:13:32 +09:00

a3e975d42e Fixes handling logic for i386/ELF GOTPC relocation 
The i386/ELF JITLink backend was not correctly handling the GOTPC relocation
by skipping the in-built addend, which was manifesting itself in the form of
a segmentation fault in the `LF_external_to_absolute_conversion.s` test. This
CR has fixed that issue.

29fe204b4e Re-apply "[JITLink] Introduce ELF/i386 backend " with correct authorship. 
I (lhames) accidentally pushed 5f300397c6ae8fa7ca3547ec2b7a3cd844f3ed59 on
Kshitij Jain's behalf without updating the patch author first (my apologies
Kshitij!).

Re-applying with correct authorship.

This reverts commit 5f300397c6ae8fa7ca3547ec2b7a3cd844f3ed59.

No functional issues, I just failed to correctly set authorship on the patch.

5f300397c6 [JITLink] Introduce ELF/i386 backend support for JITLink. 
This initial ELF/i386 JITLink backend enables JIT-linking of minimal ELF i386
object files. No relocations are supported yet.
