Bug 509966 – Empty GCC_SPECS="" overrides "Forced --as-needed" instructions.

• Status: CONFIRMED
• Product: Gentoo Linux

[Description Tom Wijsman (TomWij) (RETIRED) 2014-05-10 13:19:27 UTC]

When executing the instructions from URL, I get as a result:

 # grep -n GCC_SPECS /etc/env.d/gcc/x86_64-pc-linux-gnu-4.8.2-asneeded
1:GCC_SPECS=/usr/lib/gcc/x86_64-pc-linux-gnu/4.8.2/asneeded.specs     
7:GCC_SPECS=""                                                        

Either GCC_SPECS="" needs to be removed _or_ the instructions on the URL need to be updated; in particular, I'd like to know two things before proceeding:

1. Does GCC_SPECS support multiple spec files?
2. Should the QA instructions respect the GCC_SPECS variable or overwrite it?

Thank you very much in advance.

1. Yes, separated by ':'.  See gcc/${FILESDIR}/gcc-spec-env-r1.patch.

it's a wiki, so just make the updates to it you think are appropriate.  not a bug on the toolchain side afaict.
