From c17eb4dca5a353a9dbbb8ad6934fe57af7165e91 Mon Sep 17 00:00:00 2001 From: Clement Courbet Date: Mon, 30 Mar 2020 10:03:56 +0200 Subject: powerpc: Make setjmp/longjmp signature standard Declaring setjmp()/longjmp() as taking longs makes the signature non-standard, and makes clang complain. In the past, this has been worked around by adding -ffreestanding to the compile flags. The implementation looks like it only ever propagates the value (in longjmp) or sets it to 1 (in setjmp), and we only call longjmp with integer parameters. This allows removing -ffreestanding from the compilation flags.
