Hi all,
I am facing one issue when running GCC testsuite on GCC4.4.1.
Host machine: Fedora core 8.
target Arm- cortex a-8
GCC 4.4.1
When I execute runtest with following options:
#runtest --debug --target arm --tool_exec
arm-v7a8-linux-gnueabi-gcc --tool gcc
gcc.c-torture/compile/compile.exp=sync-1.c
--target_board=myboard_sshscp
why it fail's I am not getting it. The testcase is suppose to generate
note message :
note: '__sync_fetch_and_nand' changed semantics in GCC 4.4
The output does make warning but thereafter it fails.
I observe one thing if i write /* { dg-message "note:
'__sync_fetch_and_nand' changed semantics in GCC 4.4" "" { target
*-*-* } 0 } */
with each call of (void) __sync_fetch_and_add (&sc, 1);
the test is passed. so why it fails in original condition.
Ex. below method pass.
(void) __sync_fetch_and_add (&sc, 1);/* { dg-message "note:
'__sync_nand_and_fetch' changed semantics in GCC 4.4" "" { target
*-*-* } 0 } */
o/p of gcc.log
