[LLVMdev] ARM regression between r223766 and r223925

[İsmail Dönmez]

With trunk things got even worse while compiling a simple hello world cpp:

1.      /usr/lib/gcc/arm-linux-gnueabihf/4.9/../../../../include/c++/4.9/bits/basic_string.h:114:57:
current parser token 'other'
2.      /usr/lib/gcc/arm-linux-gnueabihf/4.9/../../../../include/c++/4.9/bits/basic_string.h:45:1:
parsing namespace 'std'
3.      /usr/lib/gcc/arm-linux-gnueabihf/4.9/../../../../include/c++/4.9/bits/basic_string.h:112:5:
parsing struct/union/class body 'basic_string'
clang-3.6: error: unable to execute command: Bus error

and dmesg agrees:

[   96.272849] Alignment trap: not handling instruction f4400add at [<b4072ffc>]
[   96.280467] Unhandled fault: alignment exception (0x801) at 0x01d7a8cc

Might this be due to the fact that I now compile with -mfpu=neon ?
