Hi all,
I'm using the latest GCC 7.1 source which I've built locally for
aarch64. Everything works fine, but I'm running into issuses using LTO.
Normally I compile our dynamic library with -ffixed-x18 and it works
fine, but with LTO enabled, register x18 is used in the output assembler.
Is there anyway to stop LTO from using certain registers?
Are you passing -ffixed-x18 to the link/lto step?
R.

Yea I tried that.
It does create a different binary, as the size is different, but the x18
register is still used.
Cheers,
John.
