From 9ba8a76f8baaa1092d60ccfbc04e7efdc207c98f Mon Sep 17 00:00:00 2001 From: Anton Korobeynikov Date: Fri, 16 Feb 2007 19:11:07 +0000 Subject: [PATCH] Add possibility to set memory limit for binaries run via libSystem. This is especially needed for bugpoint. This partly implements PR688 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34349 91177308-0d34-0410-b5e6-96231b3b80d8 --- autoconf/configure.ac | 3 ++- include/llvm/Config/config.h.in | 3 +++ include/llvm/System/Program.h | 4 +++ lib/Support/GraphWriter.cpp | 8 +++--- lib/System/Unix/Program.inc | 30 +++++++++++++++++++++++ lib/System/Win32/Program.inc | 1 + tools/bugpoint/BugDriver.cpp | 4 +-- tools/bugpoint/BugDriver.h | 3 ++- tools/bugpoint/ExecutionDriver.cpp | 4 +-- tools/bugpoint/OptimizerDriver.cpp | 3 ++- tools/bugpoint/ToolRunner.cpp | 39 +++++++++++++++++++----------- tools/bugpoint/ToolRunner.h | 12 ++++++--- tools/bugpoint/bugpoint.cpp | 6 ++++- tools/llvm-ld/llvm-ld.cpp | 8 +++--- tools/llvmc/CompilerDriver.cpp | 4 +-- tools/lto/lto.cpp | 2 +- 16 files changed, 97 insertions(+), 37 deletions(-) diff --git a/autoconf/configure.ac b/autoconf/configure.ac index ea67fea9fbc..ad73185f966 100644 --- a/autoconf/configure.ac +++ b/autoconf/configure.ac @@ -709,7 +709,8 @@ dnl=== dnl===-----------------------------------------------------------------------=== AC_CHECK_FUNCS([backtrace ceilf floorf roundf rintf nearbyintf getcwd ]) -AC_CHECK_FUNCS([getpagesize getrusage gettimeofday isatty mkdtemp mkstemp ]) +AC_CHECK_FUNCS([getpagesize getrusage getrlimit setrlimit gettimeofday]) +AC_CHECK_FUNCS([isatty mkdtemp mkstemp ]) AC_CHECK_FUNCS([mktemp realpath sbrk setrlimit strdup strerror strerror_r ]) AC_CHECK_FUNCS([strtoll strtoq sysconf malloc_zone_statistics ]) AC_CHECK_FUNCS([setjmp longjmp sigsetjmp siglongjmp]) diff --git a/include/llvm/Config/config.h.in b/include/llvm/Config/config.h.in index 2e9731e1a4a..7a52010c686 100644 --- a/include/llvm/Config/config.h.in +++ b/include/llvm/Config/config.h.in @@ -124,6 +124,9 @@ /* Define to 1 if you have the `getpagesize' function. */ #undef HAVE_GETPAGESIZE +/* Define to 1 if you have the `getrlimit' function. */ +#undef HAVE_GETRLIMIT + /* Define to 1 if you have the `getrusage' function. */ #undef HAVE_GETRUSAGE diff --git a/include/llvm/System/Program.h b/include/llvm/System/Program.h index 3c9230c9e06..cef3805370c 100644 --- a/include/llvm/System/Program.h +++ b/include/llvm/System/Program.h @@ -72,6 +72,10 @@ namespace sys { ///< expires, the child is killed and this call returns.
