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/s390/20090223-1.c | 60 ++++++++++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 gcc/testsuite/gcc.target/s390/20090223-1.c (limited to 'gcc/testsuite/gcc.target/s390/20090223-1.c') diff --git a/gcc/testsuite/gcc.target/s390/20090223-1.c b/gcc/testsuite/gcc.target/s390/20090223-1.c new file mode 100644 index 000000000..443ccb9aa --- /dev/null +++ b/gcc/testsuite/gcc.target/s390/20090223-1.c @@ -0,0 +1,60 @@ +/* The RTL loop optimizer used to replace the output register of the + inline assembly with a pseudo although the variable is declared as + register asm ("0"). */ + +/* { dg-do run } */ +/* { dg-options "-O2" } */ + +extern void abort (void); + +static unsigned char __attribute__ ((always_inline)) +mytoupper (unsigned char c) +{ + if (c >= 'a' && c <= 'z') + c -= 'a' - 'A'; + return c; +} + +static unsigned long __attribute__ ((always_inline)) +strlen (const char *s) +{ + register unsigned long r0 asm ("0"); + const char *tmp = s; + + asm ( +#ifdef __s390x__ + " lghi %0, 0\n" +#else + " lhi %0, 0\n" +#endif + "0:srst %0,%1\n" + " jo 0b" + : "=d" (r0), "+a" (tmp) + : + :"cc"); + return r0 - (unsigned long) s; +} + +char boot_command_line[] = "this is a test"; + +void __attribute__ ((noinline)) +foo (char *str) +{ + if (strcmp (str, "THIS IS A TEST") != 0) + abort (); +} + +int +main () +{ + char upper_command_line[1024]; + int i; + + for (i = 0; i < strlen (boot_command_line); i++) + upper_command_line[i] = mytoupper (boot_command_line[i]); + + upper_command_line[strlen (boot_command_line)] = 0; + foo (upper_command_line); + + return 0; +} -- cgit v1.2.3
