| | | | | | | | | | | | | Make PrologEpilogInserter save/restore all callee saved registers in functions which call __builtin_unwind_init() __builtin_unwind_init() is an undocumented gcc intrinsic which has this effect, and is used in libgcc_eh. Goes part of the way toward fixing PR8541. This obsoletes the ugly hack to libgcc's unwind code from r245272, and should also work for other arches, so revert the hack too.
* GCC: bring back experimental support for amdfam10/barcelona CPUs.pfg2013-06-0115-165/+1515
| | | | | | | | | | | | | Initial support for the AMD amdfam10 chipsets has been available in the gcc43 branch under GPLv2. AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10 support and made it available. This is a revised subset of the support initially brought in in r236962 and later reverted. The collateral efects seem to have disappeared but it is still recommended to set the CPUTYPE with caution. Reviewed by: jkim (ages ago) MFC after: 3 weeks

* 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.pfg2012-12-281-1/+1

* 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.

* Don't define CTORS_SECTION_ASM_OP and DTORS_SECTION_ASM_OP on arm whenandrew2012-12-151-0/+2
| | | | | | | | | | | | | | | | | built with clang. When these are defined the lists are defined similar to: asm(".section .ctors"); STATIC func_ptr __CTOR_LIST__[1] = { (func_ptr) (-1) }; asm(".section .dtors"); STATIC func_ptr __DTOR_LIST__[1] = { (func_ptr) (-1) }; The problem is clang will move the two arrays out of the .ctors and .dtors sections causing these sections to contain a single null address. 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.

| | | | | | | | | | | | | | | | | | | | | | | | r238211: Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb This adds a new TARGET_ARCH for building on ARM processors that support the ARMv6K multiprocessor extensions. In particular, these processors have better support for TLS and mutex operations. This mostly touches a lot of Makefiles to extend existing patterns for inferring CPUARCH from ARCH. It also configures: * GCC to default to arm1176jz-s * GCC to predefine __FreeBSD_ARCH_armv6__ * gas to default to ARM_ARCH_V6K * uname -p to return 'armv6' * make so that MACHINE_ARCH defaults to 'armv6' It also changes a number of headers to use the compiler __ARM_ARCH_XXX__ macros to configure processor-specific support routines.
