| // 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. |

| // 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. |
