esp32_exception_decoder wrong result

[smarq8]

using "monitor_filters = esp32_exception_decoder" return incorrect result in file and fileLine
for example:

0x4013c084:0x3ffced90 in TFT_eSPI::pushSwapBytePixels(void const*, unsigned int) at lib\TFT_eSPI/TFT_eSPI.cpp:3403
should be
0x4013c084: TFT_eSPI::pushSwapBytePixels(void const*, unsigned int) at lib\TFT_eSPI\Processors/TFT_eSPI_ESP32.c line 257

For comparison EspExceptionDecoder tool for Arduino seems to be correct at decoding, and I found there was some trouble with decoding fileLine mentioned here. I hope it will help somehow to solve problem.

Hi @smarq8 ! I believe it's a peculiarity of the TFT_eSPI library. They use the preprocessor to combine several source files into one compilation unit, so the backtrace seems to be technically correct, but not really informative. Although it's interesting how the tool for Arduino is capable of handling case.

@Tasssadar any chance you could take a look at this?

After further investigation I probably found interesting trace. In very short, it seems "xtensa-esp32-elf-addr2line.exe" might be outdated. Just read carefuly descrition of each code block and analyze for example file fileLine of "TFT_eSPI::pushSwapBytePixels"
decode using esp32_exception_decoder from platformio

decode using Arduino tool "EspExceptionDecoder-1.0.6" - I tested all versions from 1.0.3-1.0.6 with same result

I also dig out from my old hdd some outdated tool littleyoda/EspStackTraceDecoder and playing around with xtensa-esp32-elf-addr2line.exe I can nearly recreate result with external tools
here is decoding with ".platformio\packages\toolchain-xtensa32\bin\xtensa-esp32-elf-addr2line.exe" or "AppData\Local\Arduino15\packages\esp32\tools\xtensa-esp32-elf-gcc\gcc8_4_0-esp-2021r1\bin\xtensa-esp32-elf-addr2line.exe". It seems to be very similar to Arduino tool
