Subject: [PATCH] gcc-runtime: Fix __FILE__ related reproducablity issues
Date: Wed, 28 Apr 2021 13:14:40 -0700	[thread overview]
Message-ID: <20210428201440.1902173-1-raj.khem@gmail.com> (raw)

libstdc++ uses assertion macros which use __FILE__ macros and

  if (__builtin_expect(!bool(_Condition), false))                      \
    std::__replacement_assert(__FILE__, __LINE__, __PRETTY_FUNCTION__, \
                              #_Condition)

This ends up using absolute paths into build tree for the cases where
the charconv header is used, therefore replace the file prefix paths
with on-target paths to make them build dir independent
