* Allow the unwind functions int libgcc_s to interact correctly with libthr.andrew2013-02-041-2/+2
| | | | | | | | | | | | | | | | | | | _Unwind_ForcedUnwind in libgcc_s takes as one of it's parameters a stop function to tell it when to stop unwinding. One of the stop function's parameters is a _Unwind_Exception_Class. On most architectures this is an int64_t, however on ARM EABI the gcc developers have made this a char array with 8 items. While both of these take the same space they are passed into the stop function differently, an int64_t is passed in in registers r2 and r3, while the char[8] is passed in as a pointer to the first item in register r2. Because libthr expects the value to be an int64_t we would get incorrect results when it passes a function that take an int64_t but libgcc passes in a pointer to a char array including crashing. The fix is to update libgcc_s to make it pass an int64_t to the stop function and to libstdc++ as it expects _Unwind_Exception_Class to be an array.

| | | | | | | | | | | | | | | | | runtime on amd64, when it is compiled by clang. Some versions of clang don't save and restore all callee registers, if a __builtin_eh_return() intrinsic is used in a function. This is particularly bad on amd64. Until the problem gets fixed by upstream, use an asm statement to force clang to assume the registers in question are clobbered, when invoking __builtin_eh_return(), so it will emit code to save and restore them. This should fix the crashes reported on -current with some C++ programs, particularly those that throw exceptions over multiple function boundaries. Reported by: stefanf MFC after: 3 days

* gcc: avoid generating negative values to DW_AT_byte_size.pfg2012-12-281-3/+3
| | | | | | | | | | | | | | | | | There is a bug in gcc (GCC/35998) where dwarf reports sizes of unsigned -1 (0xffffffff). On NetBSD this generated a faulty CTF entry which then caused a segfault in ctfmerge. The issue was worked around in NetBSD's Dtrace but since the issue originated in gcc, it seems reasonable to fix it here. Upstream gcc has been slow to react to this issue and the author that submitted the patch is not interested in licensing the change to us, so I did an independent workaround for the issue.

By not defining these macros we use the version of the code that places the arrays is their sections by using __attribute__((section(".ctors"))) and similar for .dtors.
