// The purpose of this file is to glue the mismatching headers (Android NDK vs
// glibc) and therefore avoid doing otherwise awkward #ifdefs in the code.
// The following quirks are currently handled by this file:
// - MIPS: Keep using forked definitions of user.h structs. The definition in
// the NDK is completely different. Internal bug b/18097715
// - i386: Use the Android NDK but alias user_fxsr_struct > user_fpxregs_struct.
// - x86_64: Override a typo in user_fpregs_struct (mxcsr_mask -> mxcr_mask).
// The typo has been fixed in NDK r10d, but a preprocessor workaround is
// required to make breakpad build with r10c and lower (more details below).
// - Other platforms: Just use the Android NDK unchanged.

// TODO(primiano): remove this after Chromium has stably rolled to NDK r10d.
// Historical context: NDK releases < r10d had a typo in sys/user.h (mxcsr_mask
// instead of mxcr_mask), which is fixed in r10d. However, just switching to use
// the correct one (mxcr_mask) would put Breakpad in a state where it can be
// rolled in chromium only atomically with the r10d NDK. A revert of either
// project (android_tools, breakpad) would make the other one unrollable.
// This hack makes breakpad code compatible with both r10c and r10d NDKs,
// reducing the dependency entangling with android_tools.
