Changes in directory llvm/lib/Target/X86:
X86TargetAsmInfo.cpp updated: 1.39 -> 1.40
---
Log message:
Sets the section names for fixed-size constants and use the mergeable
flag for ELF on x86 so that duplicate constants can be eliminated by
the linker. This matches what GCC does with its -fmerge-constants
option, which is enabled at most -O levels.
