# Patches for binutils on SerenityOS

## `0001-Add-support-for-SerenityOS.patch`

Add support for SerenityOS

Teaches the assembler, BFD, and the linker about the SerenityOS target
triple.

We set '/' to not start a comment in GAS, as the QEMU port uses it for
division in constant expressions in assembly files (cf. as --divide).

`/usr/lib/Loader.so` is set as the default ELF interpreter.

On AArch64, we set `COMMONPAGESIZE` to enable RELRO support.

## `0002-ld-Add-Bsymbolic-non-weak-functions.patch`

ld: Add -Bsymbolic-non-weak-functions

This option is a subset of -Bsymbolic-functions: only STB_GLOBAL are
considered. Vague linkage functions are STB_WEAK. A vague linkage
function may have different addresses in a -Bsymbolic-functions linked
shared object and outside the shared object.
-Bsymbolic-non-weak-functions can keep pointer equality while providing
most benefits: (a) fewer JUMP_SLOT (symbol lookups) (b) avoid PLT
entries for default visibility defined functions.

## `0003-Set-development-to-false.patch`

Set "development" to "false"

FIXME: Remove this patch when updating to the next release.

Binutils 2.46 was accidentally packaged with this variable set to true,
which leads to build errors because this enables -Werror.
