From e780d58fd7b6eda76065327a9921d6157e4a7964 Mon Sep 17 00:00:00 2001 From: Michael Forney Date: Mon, 16 Mar 2020 12:56:56 -0700 Subject: Use breakpad_getcontext on all Linux platforms missing getcontext getcontext is also not available on musl libc, so generalize breakpad_getcontext so it can be used as a fallback for non-Android platforms as well. On x86_64 and i386, ucontext_t uses an Android-specific offset for storage of FP registers, since its sigset_t differs in size. So, make the definition of MCONTEXT_FPREGS_MEM and UCONTEXT_FPREGS_MEM_OFFSET conditional on whether we are building for Android. On glibc and musl, signal.h and asm/sigcontext.h can't be included together, so in breakpad_context_unittest.cc, only compare the libc and kernel _fpstate when on Android.
