[llvm-commits] CVS: llvm/include/llvm/Support/CommandLine.h

[Dale Johannesen]

Changes in directory llvm/include/llvm/Support:

CommandLine.h updated: 1.64 -> 1.65
---
Log message:

Make tail merging the default, except on powerPC.  There was no prior art
for a target-dependent default with a command-line override; this way
should be generally usable.
