Hello, Package gcc-5_5.2.1-15 is causing following issue during package pygccjit_0.4-4 build: test_bf_jit (test.JitTests) ... /tmp/libgccjit-HxB6hJ/fake.s: Assembler messages: /tmp/libgccjit-HxB6hJ/fake.s:14: Error: `fp=xx' used with a cpu lacking ldc1/sdc1 instructions /tmp/libgccjit-HxB6hJ/fake.s:14: Error: `fp=xx' used with a cpu lacking ldc1/sdc1 instructions /tmp/libgccjit-HxB6hJ/fake.s:15: Error: `fp=xx' used with a cpu lacking ldc1/sdc1 instructions /tmp/libgccjit-HxB6hJ/fake.s:22: Error: `fp=xx' used with a cpu lacking ldc1/sdc1 instructions /tmp/libgccjit-HxB6hJ/fake.s:24: Error: `fp=xx' used with a cpu lacking ldc1/sdc1 instructions /tmp/libgccjit-HxB6hJ/fake.s:201: Error: `fp=xx' used with a cpu lacking ldc1/sdc1 instructions /tmp/libgccjit-HxB6hJ/fake.s:202: Error: `fp=xx' used with a cpu lacking ldc1/sdc1 instructions libgccjit.so: error: error invoking gcc driver: exit_status: 256 err: 0 libgccjit.so: error: whilst attempting to run a driver named: mipsel-linux-gnu-gcc-5 libgccjit.so: error: PATH was: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin ERROR For this issue to be seen on pygccjit build log, one could rebuild package against new gcc-5 version. This issue is not noticed with gcc-5 version gcc-5_5.1.1-13 that is in pygccjit build log: https://buildd.debian.org/status/fetch.php?pkg=pygccjit&arch=mips&ver=0.4-4&stamp=1436417562 Problem that is present with gcc-5_5.1.1-13 is still there on gcc-5_5.2.1-15 and I will open a separate bug report for this issue. Here are lines that I get during package build with gcc-5_5.1.1-14: gcc-5 -shared /tmp/libgccjit-z1jPnd/fake.s -o /tmp/libgccjit-z1jPnd/fake.so -fno-use-linker-plugin and gcc-5_5.2.1-15: gcc-5 -EL -mips1 -mabi=32 -shared /tmp/libgccjit-piCaTh/fake.s -o /tmp/libgccjit-piCaTh/fake.so -fno-use-linker-plugin Notice mips1 flag in build line. I have traced back changes that caused this new issue and they are first introduces with gcc-5_5.2.1-13 version: https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/jit/jit-playback.h?r1=225207&r2=226126 https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/jit/jit-playback.c?r1=225726&r2=226126 After reverting these patches on MIPS this issue is not there any more. This is confirmed with gcc-5_5.2.1-15 built with those changes reverted. This issue is found in versions: 5.2.1-13, 5.2.1-14, 5.2.1-15, 5.2.1-16. Suggestions are welcomed. Thank you! Regards, Jurica
