libphobos: Add MIPS64 implementation of fiber_switchContext [PR118584]

2025-01-21T19:02:07+00:00

Replaces the generic implementation.  The `core.thread.fiber' module
already defines version=AsmExternal on mips64el-linux-gnuabi64.

	PR d/118584

libphobos/ChangeLog:

	* libdruntime/config/mips/switchcontext.S: Add MIPS64 N64 ABI
	implementation of fiber_switchContext.

MIPS/libphobos: Fix switchcontext.S assembly for MIPS I ISA

2020-10-12T18:09:13+00:00

Correct MIPS I assembly build errors in switchcontext.S:

.../libphobos/libdruntime/config/mips/switchcontext.S: Assembler messages:
.../libphobos/libdruntime/config/mips/switchcontext.S:50: Error: opcode not supported on this processor: mips1 (mips1) `sdc1 $f20,(0*8-((6*8+4+(-6*8+4&7))))($sp)'

etc., due to the use of the MIPS II LDC1 and SDC1 hardware instructions
for FP register load and store operations.  Instead use the L.D and S.D
generic assembly instructions, which are strict aliases for the LDC1 and
SDC1 instructions respectively and produce identical machine code where
the assembly for the MIPS II or a higher ISA has been requested, however
they become assembly macros and expand to compatible sequences of LWC1
and SWC1 hardware instructions where the assembly for the MIPS I ISA is
in effect.

	libphobos/
	* libdruntime/config/mips/switchcontext.S [__mips_hard_float]:
	Use L.D and S.D generic assembly instructions rather than LDC1
	and SDC1 MIPS II hardware instructions.

libphobos: Fix linker warning and SEGV in core.thread tests.

2019-04-24T22:46:59+00:00

The monolithic core/threadasm.S source has been removed, and split into
multiple parts, one for each intended target CPU/OS.

Added .type and .size directives for all asm implementations of
fiber_switchContent and callWithStackShell where they were missing.
