espsystem: add support for RISC-V panic backtrace Add .eh_frame and .eh_frame_hdr sections to the binary (can be enabled/disabled within menuconfig). These sections are parsed when a panic occurs. Their DWARF instructions are decoded and executed at runtime, to retrieve the whole backtrace. This parser has been tested on both RISC-V and x86 architectures. This feature needs esptool's merge adjacent ELF sections feature. 2021-01-13 23:09:40 -05:00			`#`

espsystem: Rearchitecture and fix eh_frame_parser bugs eh_frame_parser is architecture independent, thus the files have been rearchitectured. Some bugs have been fixed in the test. A README file has also been added to eh_frame_parser host test directory. eh_frame_parser is now able to detect empty gaps in .eh_frame_hdr table (missing DWARF information). Fix a bug occuring when parsing backtraces originated from abort(). Fix build missing dependencies issue. 2021-02-07 02:03:51 -05:00			`CFLAGS=-W -fasynchronous-unwind-tables -I. -I../include/ -std=c99 -g -DCONFIG_ESP_SYSTEM_USE_EH_FRAME -m32`
