Description email@example.com 2005-01-05 16:01:32 UTC
The code below passes a union (type ct1) as a var arg. The callee checks that the union is indeed received correctly by checking each field. This fails in line 38: assert (hv1.bv1 == nv1.bv1); Environment: System: IRIX64 mars 6.5 07080049 IP27 host: mips-sgi-irix6.5 build: mips-sgi-irix6.5 target: mips-sgi-irix6.5 configured with: ../configure --prefix=/usr/freeware --enable-version-specific-runtime-libs --disable-shared --enable-threads --enable-haifa --enable-libgcj --disable-c-mbchar How-To-Repeat: Compile and run the following code. The bug manifests itself with the following message: Assertion failed: EX, file foo.c, line 38

Can you test 3.4.x as there were changes to the MIPS back-end which might have fixed this.

If this question was addressed to me, the reporter of the bug: I tried to build the recent GCC from CVS on the Irix but failed. There is no more recent GCC than 3.3 installed on the machine and therefore I can't easily run the test. This machine is part of our computing center and I don't know much about it. Building GCC is also a challenge because it exceeds my quotas and I have to ask for special permissions first (even when building in /tmp). -- Christian

Just to confirm that the testcase fails with 3.3.x but works with 3.4.x and current CVS. We can't really make ABI changes to a stable branch so I'm closing this as fixed.
