Description dank 2003-07-19 18:32:12 UTC

I'm building and testing cross-compilers using http://kegel.com/crosstool

Both gcc-3.3 and gcc-ss-3_3-20030714's 'make check-gcc' produce
the following error:

FAIL: gcc.dg/duff-2.c (test for excess errors)
Excess errors:
/crosstool-0.13/build/powerpc-750-linux-gnu/gcc-3.3-glibc-2.2.5/gcc-3.3/gcc/testsuite/gcc.dg/duff-2.c:28:
warning: unreachable code at beginning of switch statement

This looks like PR 5230 but on a different platform.
I haven't tested an x86 compiler.
It also looks similar to PR 11370.

I can confirm this in 3.3.1 (20030714) but on the mainline (20030719), it is
already fixed, 
this on powerpc-*linux-gnu, I have not checked with sh4-*-linux-gnu yet.

Since this is only a diagnostic problem closing as Mark is closing diagnostic
problems.

Comment 3 Andrew Pinski 2003-09-17 22:07:10 UTC

I should have said which are already fixed on the mainline.
