[llvm-commits] CVS: llvm/test/CodeGen/X86/test-pic-6.ll

[Anton Korobeynikov]

Changes in directory llvm/test/CodeGen/X86:

test-pic-6.ll added (r1.1)
---
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.
