[llvm-commits] CVS: llvm/lib/Support/CommandLine.cpp

[Dale Johannesen]

Changes in directory llvm/lib/Support:

CommandLine.cpp updated: 1.87 -> 1.88
---
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.
