[llvm-commits] CVS: gcc-3.4/gcc/llvm-expand.c

[John Criswell]

Changes in directory gcc-3.4/gcc:

llvm-expand.c updated: 1.16 -> 1.17

---
Log message:

For array references, try to cast the integer reference into the proper
signed integer type that matches the machines pointer size.  This ensures
proper sign extension when the references are converted to LLVM longs
(i.e. 64 bits).

This is a fix for PR#268.

Regretably, this still doesn't fix the Homebrew Decompiler (hbd).
:(
