The libc softfloat implementation is preferred over the one in libgcc as it implements rounding modes and floating point exceptions. ok patrick@ Switch OpenBSD/armv7 to ARM EABI (soft-float).

Fundamentally this causes a link dependency on libc that we'll not always be able to satisfy. Spotted by deraadt@. OK matthew@, kettenis@, guenther@. A port of the current gcc 3.3.6 m88k backend to gcc 4.2.1. 2013-05-08T15:30:38Z miod miod@openbsd.org 2013-05-08T15:30:38Z urn:sha1:1f5e8f306e060fa0973ecf2246bc083d30a1ca13 Main features: - md constraints rewritten in RTL - md predicaties rewritten in RTL - md va_arg switched to gimple - abort() calls replaced with gcc_assert() or gcc_unreachable() for better diagnostics - support for non-ELF systems completely removed Missing: - conversion of the pipeline information from define_function_unit to define_automata not done yet (thus pipeline information currently removed) Known regressions against 3.3.6 so far: - no stack protector support yet - __builtin_setjmp doesn't restore the frame pointer correctly upon return from __builtin_longjmp - at least one case of optimization error when delay slots are not disabled. - libgcc is only built -fPIC, instead of static/fpic/fPIC. Add __ic_invalidate_array to libgcc on sh. 2012-05-04T17:50:41Z kettenis kettenis@openbsd.org 2012-05-04T17:50:41Z urn:sha1:bba893b832b8f8407a5666430e6215e8fbb31b49 ok miod@, jsg@ Explicitely request -fno-stack-protector on sh when building the unwinder, 2012-04-17T11:09:16Z miod miod@openbsd.org 2012-04-17T11:09:16Z urn:sha1:2bc9967877ea31aaf74143c98bfa3f759aad9e19 for unwind-dw2.c fails to build otherwise. the fpu control symbol on sh (__fpscr_values) suddenly becomes local 2012-04-12T11:28:32Z jsg jsg@openbsd.org 2012-04-12T11:28:32Z urn:sha1:5db72d50120c7aa6e3bf540d4c9845bc08e685db instead of global with gcc4 and this ends up breaking things in hard to debug ways.
