Only emit debug info when asked

[antoyo]

Currently, debug info is always emmited.

• context.set_debug_info(true); should not always be called in src/base.rs.
• -Cdebuginfo=2 should probably not be always added in build_system/src/config.rs.

@antoyo please i will love to work on this issue and submit the PR to link as we discuss earlier in the mail

[antoyo]

Good. Feel free to ask any questions if you need help.

@antoyo if i understand the config.rs file correctly RUSTFLAGS is what collect all the the environment variables and join them into string, thus removing the "-Cdebuginfo=2" from vector, mean the debug option will not get emitted

[bjorn3]

The standard library shipped with rustup is built with -Cdebuginfo=1.

[mubarak23]

@bjorn3 i see, does this mean, -Cdebuginfo=1 will not emit debug information, while -Cdebuginfo=2 emit debug information

[bjorn3]

-Cdebuginfo=1 only emits the line tables part of the debug info (+ some other things), while -Cdebuginfo=2 emits all debug info. Now that I'm taking a closer look, I see that debuginfo is already enabled for the standard library outside of the -Cdebuginfo=2 your PR removes, so I think your PR is fine. (It is enabled for the standard library at

rustc_codegen_gcc/build_sysroot/Cargo.toml

Line 21 in 7ff5d39

debug = true

)

[antoyo]

This will emit all debug info, though, so we might as well change this to:

debug = "limited"

@mubarak23: Could you please add this change to your PR?

[mubarak23]

@antoyo i will add it to the PR and push
