From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- boehm-gc/tests/leak_test.c | 22 + boehm-gc/tests/middle.c | 25 + boehm-gc/tests/staticrootslib.c | 33 + boehm-gc/tests/staticrootstest.c | 46 + boehm-gc/tests/test.c | 1855 +++++++++++++++++++++++++++++++++++++ boehm-gc/tests/test_cpp.cc | 288 ++++++ boehm-gc/tests/thread_leak_test.c | 41 + boehm-gc/tests/trace_test.c | 30 + 8 files changed, 2340 insertions(+) create mode 100644 boehm-gc/tests/leak_test.c create mode 100644 boehm-gc/tests/middle.c create mode 100644 boehm-gc/tests/staticrootslib.c create mode 100644 boehm-gc/tests/staticrootstest.c create mode 100644 boehm-gc/tests/test.c create mode 100644 boehm-gc/tests/test_cpp.cc create mode 100644 boehm-gc/tests/thread_leak_test.c create mode 100644 boehm-gc/tests/trace_test.c (limited to 'boehm-gc/tests') diff --git a/boehm-gc/tests/leak_test.c b/boehm-gc/tests/leak_test.c new file mode 100644 index 000000000..bf563ac1c --- /dev/null +++ b/boehm-gc/tests/leak_test.c @@ -0,0 +1,22 @@ +#include "leak_detector.h" + +int main() { + int *p[10]; + int i; + GC_find_leak = 1; /* for new collect versions not compiled */ + /* with -DFIND_LEAK. */ + for (i = 0; i < 10; ++i) { + p[i] = malloc(sizeof(int)+i); + } + CHECK_LEAKS(); + for (i = 1; i < 10; ++i) { + free(p[i]); + } + for (i = 0; i < 9; ++i) { + p[i] = malloc(sizeof(int)+i); + } + CHECK_LEAKS(); + CHECK_LEAKS(); + CHECK_LEAKS(); + return 0; +} diff --git a/boehm-gc/tests/middle.c b/boehm-gc/tests/middle.c new file mode 100644 index 000000000..5d9360af5 --- /dev/null +++ b/boehm-gc/tests/middle.c @@ -0,0 +1,25 @@ +/* + * Test at the boundary between small and large objects. + * Inspired by a test case from Zoltan Varga. + */ +#include +#include + +int main () +{ + int i; + + GC_all_interior_pointers = 0; + + for (i = 0; i < 20000; ++i) { + GC_malloc_atomic (4096); + GC_malloc (4096); + } + for (i = 0; i < 20000; ++i) { + GC_malloc_atomic (2048); + GC_malloc (2048); + } + printf("Final heap size is %ld\n", GC_get_heap_size()); + return 0; +} + diff --git a/boehm-gc/tests/staticrootslib.c b/boehm-gc/tests/staticrootslib.c new file mode 100644 index 000000000..6e13278a6 --- /dev/null +++ b/boehm-gc/tests/staticrootslib.c @@ -0,0 +1,33 @@ +#include + +#ifndef GC_DEBUG +# define GC_DEBUG +#endif + +#include "gc.h" + +struct treenode { + struct treenode *x; + struct treenode *y; +} * root[10]; + +struct treenode * libsrl_mktree(int i) +{ + struct treenode * r = GC_MALLOC(sizeof(struct treenode)); + if (0 == i) return 0; + if (1 == i) r = GC_MALLOC_ATOMIC(sizeof(struct treenode)); + r -> x = libsrl_mktree(i-1); + r -> y = libsrl_mktree(i-1); + return r; +} + +void * libsrl_init(void) +{ + GC_INIT(); + return GC_MALLOC(sizeof(struct treenode)); +} + +void * libsrl_collect (void) +{ + GC_gcollect(); +} diff --git a/boehm-gc/tests/staticrootstest.c b/boehm-gc/tests/staticrootstest.c new file mode 100644 index 000000000..68ff9eaea --- /dev/null +++ b/boehm-gc/tests/staticrootstest.c @@ -0,0 +1,46 @@ +#include + +#ifndef GC_DEBUG +# define GC_DEBUG +#endif + +#include "gc.h" +#include "gc_backptr.h" + +struct treenode { + struct treenode *x; + struct treenode *y; +} * root[10]; + +static char *staticroot = 0; + +extern struct treenode * libsrl_mktree(int i); +extern void * libsrl_init(void); +extern void * libsrl_collect (void); + +int main(void) +{ + int i; + staticroot = libsrl_init(); + for (i = 0; i < sizeof(struct treenode); ++i) { + staticroot[i] = 0x42; + } + libsrl_collect(); + for (i = 0; i < 10; ++i) { + root[i] = libsrl_mktree(12); + libsrl_collect(); + } + for (i = 0; i < sizeof(struct treenode); ++i) { + if (staticroot[i] != 0x42) + return -1; + } + for (i = 0; i < 10; ++i) { + root[i] = libsrl_mktree(12); + libsrl_collect(); + } + for (i = 0; i < sizeof(struct treenode); ++i) { + if (staticroot[i] != 0x42) + return -1; + } + return 0; +} diff --git a/boehm-gc/tests/test.c b/boehm-gc/tests/test.c new file mode 100644 index 000000000..1180ab152 --- /dev/null +++ b/boehm-gc/tests/test.c @@ -0,0 +1,1855 @@ +/* + * Copyright 1988, 1989 Hans-J.
