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. --- gcc/testsuite/gcc.c-torture/execute/20020402-3.c | 81 ++++++++++++++++++++++++ 1 file changed, 81 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/20020402-3.c (limited to 'gcc/testsuite/gcc.c-torture/execute/20020402-3.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/20020402-3.c b/gcc/testsuite/gcc.c-torture/execute/20020402-3.c new file mode 100644 index 000000000..eef274093 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/20020402-3.c @@ -0,0 +1,81 @@ +/* extracted from gdb sources */ + +typedef unsigned long long CORE_ADDR; + +struct blockvector; + +struct symtab { + struct blockvector *blockvector; +}; + +struct sec { + void *unused; +}; + +struct symbol { + int len; + char *name; +}; + +struct block { + CORE_ADDR startaddr, endaddr; + struct symbol *function; + struct block *superblock; + unsigned char gcc_compile_flag; + int nsyms; + struct symbol syms[1]; +}; + +struct blockvector { + int nblocks; + struct block *block[2]; +}; + +struct blockvector *blockvector_for_pc_sect(register CORE_ADDR pc, + struct symtab *symtab) +{ + register struct block *b; + register int bot, top, half; + struct blockvector *bl; + + bl = symtab->blockvector; + b = bl->block[0]; + + bot = 0; + top = bl->nblocks; + + while (top - bot > 1) + { + half = (top - bot + 1) >> 1; + b = bl->block[bot + half]; + if (b->startaddr <= pc) + bot += half; + else + top = bot + half; + } + + while (bot >= 0) + { + b = bl->block[bot]; + if (b->endaddr > pc) + { + return bl; + } + bot--; + } + return 0; +} + +int main(void) +{ + struct block a = { 0, 0x10000, 0, 0, 1, 20 }; + struct block b = { 0x10000, 0x20000, 0, 0, 1, 20 }; + struct blockvector bv = { 2, { &a, &b } }; + struct symtab s = { &bv }; + + struct blockvector *ret; + + ret = blockvector_for_pc_sect(0x500, &s); + + return 0; +} -- cgit v1.2.3
