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.target/arm/pr43698.c | 38 ++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 gcc/testsuite/gcc.target/arm/pr43698.c (limited to 'gcc/testsuite/gcc.target/arm/pr43698.c') diff --git a/gcc/testsuite/gcc.target/arm/pr43698.c b/gcc/testsuite/gcc.target/arm/pr43698.c new file mode 100644 index 000000000..407cf7eac --- /dev/null +++ b/gcc/testsuite/gcc.target/arm/pr43698.c @@ -0,0 +1,38 @@ +/* { dg-do run } */ +/* { dg-options "-Os -march=armv7-a" } */ +#include +#include + + +char do_reverse_endian = 0; + +# define bswap_32(x) \ + ((((x) & 0xff000000) >> 24) | \ + (((x) & 0x00ff0000) >> 8) | \ + (((x) & 0x0000ff00) << 8) | \ + (((x) & 0x000000ff) << 24)) + +#define EGET(X) \ + (__extension__ ({ \ + uint64_t __res; \ + if (!do_reverse_endian) { __res = (X); \ + } else if (sizeof(X) == 4) { __res = bswap_32((X)); \ + } \ + __res; \ + })) + +void __attribute__((noinline)) X(char **phdr, char **data, int *phoff) +{ + *phdr = *data + EGET(*phoff); +} + +int main() +{ + char *phdr; + char *data = (char *)0x40164000; + int phoff = 0x34; + X(&phdr, &data, &phoff); + if (phdr != (char *)0x40164034) + abort (); + exit (0); +} -- cgit v1.2.3
