[llvm-commits] CVS: llvm/include/llvm/Target/TargetAsmInfo.h TargetOptions.h

[Anton Korobeynikov]

Changes in directory llvm/include/llvm/Target:

TargetAsmInfo.h updated: 1.20 -> 1.21
TargetOptions.h updated: 1.11 -> 1.12
---
Log message:

* Fix one more bug in PIC codegen: extra load is needed for *all* 
non-statics.
* Introduce new option to output zero-initialized data to .bss section. 
This can reduce size of binaries. Enable it by default for ELF & 
Cygwin/Mingw targets. Probably, Darwin should be also added.
