From 56acecdb2b1bd10222bdbe59d2483cb110c06109 Mon Sep 17 00:00:00 2001 From: Andres Freund Date: Sun, 31 Jul 2022 18:38:27 -0700 Subject: [PATCH] tools build: Add feature test for init_disassemble_info API changes commit cfd59ca91467056bb2c36907b2fa67b8e1af9952 upstream. binutils changed the signature of init_disassemble_info(), which now causes compilation failures for tools/{perf,bpf}, e.g. on debian unstable. Relevant binutils commit: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=60a3da00bd5407f07 This commit adds a feature test to detect the new signature. Subsequent commits will use it to fix the build failures.
