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/pr31448.c | 36 +++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/pr31448.c (limited to 'gcc/testsuite/gcc.c-torture/execute/pr31448.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/pr31448.c b/gcc/testsuite/gcc.c-torture/execute/pr31448.c new file mode 100644 index 000000000..720ba926e --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/pr31448.c @@ -0,0 +1,36 @@ +/* PR middle-end/31448, this used to ICE during expand because + reduce_to_bit_field_precision was not ready to handle constants. */ + +typedef struct _st { + int iIndex : 24; + int iIndex1 : 24; +} st; +st *next; +void g(void) +{ + st *next = 0; + int nIndx; + const static int constreg[] = { 0,}; + nIndx = 0; + next->iIndex = constreg[nIndx]; +} +void f(void) +{ + int nIndx; + const static int constreg[] = { 0xFEFEFEFE,}; + nIndx = 0; + next->iIndex = constreg[nIndx]; + next->iIndex1 = constreg[nIndx]; +} +int main(void) +{ + st a; + next = &a; + f(); + if (next->iIndex != 0xFFFEFEFE) + __builtin_abort (); + if (next->iIndex1 != 0xFFFEFEFE) + __builtin_abort (); + return 0; +} + -- cgit v1.2.3
