From b1b96a784632f71928220117624a2c07ab3ca9e6 Mon Sep 17 00:00:00 2001 From: Martin Nowack Date: Tue, 13 Aug 2013 12:22:36 +0200 Subject: Port to LLVM 3.3 Major changes are: - Switching to llvm-link to build archive files - Use GetMallocUsage instead of GetTotalMemoryUsage (be aware of bug in LLVM 3.3 http://llvm.org/bugs/show_bug.cgi?id=16847) - intrinsic library functions like memcpy/mov/set use weak linkage to be replaced by e.g. uclibc functions - rewrote linking with library - enhanced MemoryLimit test case to check if mallocs were successful --- runtime/Intrinsic/Makefile | 1 + runtime/Intrinsic/memcpy.c | 2 +- runtime/Intrinsic/memmove.c | 2 +- runtime/Intrinsic/mempcpy.c | 3 +-- runtime/Intrinsic/memset.c | 3 +-- 5 files changed, 5 insertions(+), 6 deletions(-) (limited to 'runtime/Intrinsic') diff --git a/runtime/Intrinsic/Makefile b/runtime/Intrinsic/Makefile index 849bfeee..3c6b01b3 100644 --- a/runtime/Intrinsic/Makefile +++ b/runtime/Intrinsic/Makefile @@ -17,6 +17,7 @@ BYTECODE_LIBRARY=1 DEBUG_RUNTIME=1 NO_PEDANTIC=1 +MODULE_NAME=kleeRuntimeIntrinsic C.Flags += -fno-builtin include $(LEVEL)/Makefile.common diff --git a/runtime/Intrinsic/memcpy.c b/runtime/Intrinsic/memcpy.c index 7f7f133d..bd9f3e38 100644 --- a/runtime/Intrinsic/memcpy.c +++ b/runtime/Intrinsic/memcpy.c @@ -9,7 +9,7 @@ #include -void *memcpy(void *destaddr, void const *srcaddr, size_t len) { +__attribute__((weak)) void *memcpy(void *destaddr, void const *srcaddr, size_t len) { char *dest = destaddr; char const *src = srcaddr; diff --git a/runtime/Intrinsic/memmove.c b/runtime/Intrinsic/memmove.c index c6e1ada9..e89abf7d 100644 --- a/runtime/Intrinsic/memmove.c +++ b/runtime/Intrinsic/memmove.c @@ -9,7 +9,7 @@ #include -void *memmove(void *dst, const void *src, size_t count) { +__attribute__((weak)) void *memmove(void *dst, const void *src, size_t count) { char *a = dst; const char *b = src; diff --git a/runtime/Intrinsic/mempcpy.c b/runtime/Intrinsic/mempcpy.c index 31e142d9..e47a94b1 100644 --- a/runtime/Intrinsic/mempcpy.c +++ b/runtime/Intrinsic/mempcpy.c @@ -8,8 +8,7 @@ //===----------------------------------------------------------------------===// #include - -void *mempcpy(void *destaddr, void const *srcaddr, size_t len) { +__attribute__((weak)) void *mempcpy(void *destaddr, void const *srcaddr, size_t len) { char *dest = destaddr; char const *src = srcaddr; diff --git a/runtime/Intrinsic/memset.c b/runtime/Intrinsic/memset.c index bef85e6a..c21f1fa9 100644 --- a/runtime/Intrinsic/memset.c +++ b/runtime/Intrinsic/memset.c @@ -8,8 +8,7 @@ //===----------------------------------------------------------------------===// #include - -void *memset(void * dst, int s, size_t count) { +__attribute__ ((weak)) void *memset(void * dst, int s, size_t count) { volatile char * a = dst; while (count-- > 0) *a++ = s; -- cgit 1.4.1
