2004-09-24Updated the last two header files so that they are configured withJohn Criswell
AC_CONFIG_HEADERS. This should prevent LLVM from needlessly re-compiling on a re-configure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16510 91177308-0d34-0410-b5e6-96231b3b80d8

2004-09-24Configure Datatypes.h.in with AC_CONFIG_HEADERS. This should prevent itJohn Criswell
from being re-generated if the new version is identical to the old version. Hence, it should save us some recompiling after re-configures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16506 91177308-0d34-0410-b5e6-96231b3b80d8

2004-09-23Fix the last of the major PPC GEP folding deficiencies. This will allowNate Begeman
the ISel to use indexed and non-zero immediate offsets for GEPs that have more than one use.

2004-09-21Don't attempt to (illegally) configure a subdir if we don't recognize it.Reid Spencer
Instead just create a warning message that says the directory cannot be configured because it isn't recognized. This also gets rid of a bunch of warning messages from the auto* tools. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16463 91177308-0d34-0410-b5e6-96231b3b80d8
2004-09-21Fix the program passed to AC_LANG_PROGRAM to be only the BODY of the mainReid Spencer
function, not the whole main function. This problem resulted during conversion of scripts to the new autoconf standard. The effect was that the mmap_file test would fail and if it does there is currently an #ifdef'd #error that causes compilation to fail. Bad, bad, bad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16462 91177308-0d34-0410-b5e6-96231b3b80d8
