1703330 - Not all rust code is included in Pernosco session

Status: RESOLVED WORKSFORME

(Firefox Build System :: General, defect)

Description

[Tyson Smith [:tsmith]]

I am seeing optimized out rust code in Pernosco sessions. An example can be found here: https://pernos.co/debug/J0BqJvtp3LFuB_LZJ1MheQ/index.html

The mozconfig used for the builds includes:

export MOZ_DEBUG_SYMBOLS=1
ac_add_options --enable-debug-symbols
ac_add_options --enable-optimize="-O0 -g"

I'm not sure if additional flags are needed to disable optimization of rust code or if flags are not being passed correctly.

export MOZ_DEBUG_SYMBOLS=1
ac_add_options --enable-debug-symbols

There are redundant and are the default

ac_add_options --enable-optimize="-O0 -g"

Try --disable-optimize instead, that should also disable it for rust. There might be a case for configure to try to detect the right thing based on the arbitrary set of flags passed to --enable-optimize, but that might be too much magic.

That is a better solution, thank you!
