Re: [PATCH 1/1] gensymlist: fix clang build with exporting of __builtin_trap

[Vladimir 'phcoder' Serbinenko]

Correct solution is to provide __builtin_trap ourselves. Likely it would be a wrapper around grub_abort

Le mar. 14 juin 2022, 15:37, Darren Kenny <darren.kenny@oracle.com> a écrit :

clang expands the abort function to __builtin_trap, but that cannot be
exported.

The script that generates the symlist.c file should also exclude any
symbols that start with __builtin_.
