Hi,
I tried to reproduce the error with a reduced test-case:
#include "arm_neon.h"
float32x2_t a, b, c, e;
int main()
{
e = __builtin_neon_vmls_lanev2sf (a, b, c, 0);
return 0;
}
arm-linux-gnueabihf-gcc -mfpu=neon test.c -flto test.c -c
arm-linux-gnueabihf-gcc test.o -flto -o test
lto1: fatal error: target specific builtin not available
compilation terminated.
lto-wrapper: fatal error:
/home/prathamesh.kulkarni/gnu-toolchain/gcc-chromium-arm-linux-gnueabihf/builds/destdir/x86_64-unknown-linux-gnu/bin/arm-linux-gnueabihf-gcc
returned 1 exit status
compilation terminated.
However passing -mfpu=neon for linking works:
arm-linux-gnueabihf-gcc -mfpu=neon test.o -flto -o test
I suppose similar thing must be happening during linking
libshared_memory_support.so for chromium build ?
I couldn't see -mfpu=neon in the command line used for linking
libshared_memory_support.so
Thank you,
Prathamesh
