Subject: perf tools: Fix unwind build on i386
|
||||
Forwarded: no
|
||||
|
||||
EINVAL may not be defined when building unwind-libunwind.c with
|
||||
REMOTE_UNWIND_LIBUNWIND, resulting in a compiler error in
|
||||
LIBUNWIND__ARCH_REG_ID(). Its only caller, access_reg(), only checks
|
||||
for a negative return value and doesn't care what it is. So change
|
||||
-EINVAL to -1.
|
||||
|
||||
Fixes: 52ffe0ff02fc ("Support x86(32-bit) cross platform callchain unwind.")
