nodejs-13.7.0 fails with ld.gold linker #31520
Comments
Similar to #31249. |
It's not quite the same as #31249, although you'll get the same link errors when you remove the I don't have time to look into it today but we probably don't need the linker script if we switch to the Caveat emptor: they're not completely interchangeable because there are a number of sections in between. |
`__executable_start` is provided by GNU's and LLVM's default linker scripts, obviating the need to plug in a custom linker script. The problem with our bespoke linker script is that it works with ld.bfd but not ld.gold and cannot easily be ported because the latter linker doesn't understand the `INSERT BEFORE` directive. The /proc/self/maps scanner is updated to account for the fact that there are a number of sections between `&__executable_start` and the start of the .text section. Fortunately, those sections are all mapped into the same memory segment so we only need to look at the next line to find the start of our text segment. Fixes: nodejs#31520

linking fails with ld.gold (binutils-2.33.1) in this way:
switching to ld.bfd yields in a error-less compilation and installation on gentoo.
Forcing the ld.bfd linker was done by prepending
LDFLAGS="${LDFLAGS} -Wl,-fuse-ld=bfd"
to the emerge command.Searching around I found this:
https://lists.gnu.org/archive/html/bug-binutils/2016-12/msg00035.html
https://bugzilla.redhat.com/show_bug.cgi?id=927573
https://sourceware.org/bugzilla/show_bug.cgi?id=15373
Which says that ld.gold does not support the Insert statement in linker scripts.
If you want me to test something, please feel free to do so.
