Jim Mussared	710426024a	all: Factor gchelper code to one place and use it for unix & ARM ports. No functionality change is intended with this commit, it just consolidates the separate implementations of GC helper code to the lib/utils/ directory as a general set of helper functions useful for any port. This reduces duplication of code, and makes it easier for future ports or embedders to get the GC implementation correct. Ports should now link against gchelper_native.c and either gchelper_m0.s or gchelper_m3.s (currently only Cortex-M is supported but other architectures can follow), or use the fallback gchelper_generic.c which will work on x86/x64/ARM. The gc_helper_get_sp function from gchelper_m3.s is not really GC related and was only used by cc3200, so it has been moved to that port and renamed to cortex_m3_get_sp.	2020-04-29 23:45:19 +10:00
Damien George	f608f54ab0	lib/utils/gchelper_m3: Add gc_helper_get_sp() function.	2019-02-12 14:37:01 +11:00
Damien George	90e1303b2d	lib/utils/gchelper_m3: Add license header and clean up code. This file generates the same code with the cortex-m3 and cortex-m4 assembler directive, so use cortex-m3 to support more CPUs.	2019-02-12 14:16:24 +11:00
Damien George	e6d97e8a0b	stm32: Move gchelper assembler code to lib/utils for use by other ports.	2019-02-12 14:11:21 +11:00
