Bug Description

Using the linaro build 2014.05 of the Aarch64 toolchain the floating point benchmark 191.fma3d failed to compile.

Forgot to note that this is a regression with respect to the 2104.04 release of the AArch64 toolchain.

Changed in gcc-linaro:
assignee: nobody → Kugan Vivekanandarajah (kugan-vivekanandarajah)

Is this reproducible with 4.9-2014.05 also? what version of 2104.04 did you use? Can you please provide the gcc -v and the exact compiler option that can be used to reproduce this.

The bug is reproducible, I eliminated one of the flags (see below) and got the same error.

This bug is against the 4.9-2014.05 aarch64 toolchain. This did NOT happen in the 4.8-21014.04 aarch64 toolchain.

fma3d code is Fortran.

Following is extracted from the SPEC config file that I used to build the cpu2000 floating-point binaries
191.fma3d=default=default=default:
FOPTIMIZE = -O3 -march=armv8-a+crypto -ffast-math -ftree-vectorize -fno-use-linker-plugin -floop-interchange -static -g

and had the same problem after removing -floop-interchange
FOPTIMIZE = -O3 -march=armv8-a+crypto -ffast-math -ftree-vectorize -fno-use-linker-plugin -static -g

The same-looking bug reported against AOSP: https://bugs.linaro.org/show_bug.cgi?id=373

Since bugzilla is now the default place for bugs in Linaro toolchains, bugs.linaro.org shall be the place to track this problem.

Thank you.

I cant reproduce this with Linaro GCC 2014.09. with:

CC = /home/tcwg/kugan/cbuild/builds/destdir/aarch64-unknown-linux-gnu/bin/aarch64-none-linux-gnu-gcc -Wl,--dynamic-linker=/home/tcwg/kugan/cbuild/builds/sysroot-aarch64-none-linux-gnu/lib/ld-linux-aarch64.so.1 -Wl,-rpath=/home/tcwg/kugan/cbuild/builds/sysroot-aarch64-none-linux-gnu/libc/lib/aarch64-linux-gnu:/home/tcwg/kugan/cbuild/builds/sysroot-aarch64-none-linux-gnu/lib

COPTIMIZE = -O3 -march=armv8-a+crypto -ffast-math -ftree-vectorize -fno-use-linker-plugin -flto -fno-common -mcpu=cortex-a57

Please let me know with the exact command line you used in the spec config to reproduce.

Please also note that we are now using https://bugs.linaro.org/ for tracking bugs. If you still see this regression we should take it there.
