From ae17e42b368768ec333e259241be6c2c9153f731 Mon Sep 17 00:00:00 2001 From: Gabor Greif Date: Tue, 11 Aug 2009 00:59:39 +0000 Subject: [PATCH] Lay the groundwork for my upcoming ilist sentinel shrinking patch by defining a LLVM_COMPACT_SENTINELS symbol to 0 or 1 in config.h. I'm asking for 3 favors: - may an autofoo expert look at this and suggest improvements? - may a cmake expert suggest analogous functionality for config.h? - may somebody with the right autofoo mix regenerate configure? (mine is too new) Thanks! --This line, and those below, will be ignored-- M configure.ac llvm-svn: 78628 --- autoconf/configure.ac | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/autoconf/configure.ac b/autoconf/configure.ac index 063faa6c488..149ddd1e027 100644 --- a/autoconf/configure.ac +++ b/autoconf/configure.ac @@ -312,6 +312,17 @@ else AC_SUBST(DISABLE_ASSERTIONS,[[DISABLE_ASSERTIONS=1]]) fi +dnl LLVM_COMPACT_SENTINELS : can be used to shrink ilist's end iterators and disable certain checks on them: +if test ${ENABLE_OPTIMIZED},${DISABLE_ASSERTIONS} = "ENABLE_OPTIMIZED=1,DISABLE_ASSERTIONS=1" ; then + AC_SUBST(LLVM_COMPACT_SENTINELS,[1]) +else + AC_SUBST(LLVM_COMPACT_SENTINELS,[0]) +fi + +AC_DEFINE_UNQUOTED([LLVM_COMPACT_SENTINELS],$LLVM_COMPACT_SENTINELS, + [Define to 1 for ilist sentinel compaction]) + + dnl --enable-expensive-checks : check whether they want to turn on expensive debug checks: AC_ARG_ENABLE(expensive-checks,AS_HELP_STRING( --enable-expensive-checks,[Compile with expensive debug checks enabled (default is NO)]),, enableval="no")
