Bug ID: 70136
Summary: -march=native causes SIGABRT due to double close of
FILE on certain ARM systems (BCM2834, armv8
cortex-a53)
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: andrewm.roberts at sky dot com
Target Milestone: ---
gcc 4.9.1 (Raspbian Linux)
gcc 5.3.0 (Arch Linux)
gcc 6-20160306 (Arch Linux)
all crash on Raspberry Pi 3 (BCM2834, armv8 cortex-a53) when using
-march=native compiler flag.
To reproduce:
echo "int main(void) {return0;}" | gcc -c -x c -march=native -
Example output (gcc 5.3.0):
[alarm@alarmp ~]$ echo "int main(void) {return 0;}" | gcc -c -x c -march=native
-

using intree: mfpr-3.1.4, isl-0.16.1, gmp-6.1.0, mpc-1.0.3
( NOTE 2 GCC BUILD BUGS HERE
1) had to run autoreconf on isl it wanted automake 1.14.1 and wouldn't build
with automake 1.15. This is the isl from gcc infrastructure page.
2) after configure had to fix makefile in gcc due to bug, as mentioned here:
https://sourceware.org/bugzilla/attachment.cgi?id=6807
# Workaround for a problem introduced with GMP 5.1.0.
# If configured by gcc with the "none" host & target, it will result in
undefined references to '__gmpn_invert_limb' during linking.
# Should be fixed by next version of gcc, but let me know if you have any more
ideas on this.
