[llvm-commits] CVS: llvm/autoconf/m4/path_tclsh.m4

[Reid Spencer]

Changes in directory llvm/autoconf/m4:

path_tclsh.m4 added (r1.1)
---
Log message:

Add a check for the tclsh program needed by dejagnu. This can have weird
names that have version numbers in it so this macro, DJ_AC_PATH_TCLSH will
make the necessary checks. The makefile variable TCLSH is set to the path
found.

+ dnl This macro checks for tclsh which is required to run dejagnu. On some 
+ dnl platforms (notably FreeBSD), tclsh is named tclshX.Y - this handles
+ dnl that for us so we can get the latest installed tclsh version.
