Details:

 

test gcc.dg/tree-ssa/20040204-1.c is an unexpected successes.

 

This XPASS always exists and it's not a regression bug.

Executing on host: bfin-elf-gcc /home/test/work/cruise/checkouts/toolchain/gcc-4.3/gcc/testsuite/gcc.dg/tree-ssa/20040204-1.c   -O1 -fdump-tree-optimized -fno-show-column -S  -msim  -o 20040204-1.s    (timeout = 300)

 

spawn bfin-elf-gcc /home/test/work/cruise/checkouts/toolchain/gcc-4.3/gcc/testsuite/gcc.dg/tree-ssa/20040204-1.c -O1 -fdump-tree-optimized -fno-show-column -S -msim -o 20040204-1.s

 

PASS: gcc.dg/tree-ssa/20040204-1.c (test for excess errors)

XPASS: gcc.dg/tree-ssa/20040204-1.c scan-tree-dump-times optimized "link_error" 0

Follow-ups

When compiled with the bfin- compilers the calls to link_error are correctly

optimized away. The native ix86 4.3 compiler fails to do this (leaving a call to

link_error in the function test55).

It could be that the 4.3 head has regressed on this, or that we have a blackfin

specific optimization that removes the function call. Either way, our compiler

is doing nothing wrong and this isn't a bug.

Unless there are any objections I will mark the test as a PASS for bfin-*-*?

going by the comments in the source file, that sounds OK to me

Dave:

 

If you are going to update status/shift assignment to people  - you need to

leave a comment - otherwise no one knows.

 

Thanks

OK, it's pass now. Close it.
