==========
|
||||
|
||||
This is the most recent version of GCC. With this version of GCC, the
|
||||
final gcc-binutils-musl toolchain is complete. The focus of further builds
|
||||
shifts to rebuilds for correctness, cleanup and preparation for downstream
|
||||
consumption.
|
||||
|
||||
In line with this, a variety of modern features + minor build changes are used
|
||||
to ensure the compiler is suitable for downstream consumption;
|
||||
|
||||
* A full internal GCC bootstrap is used to ensure there are no lagging
|
||||
historical problems.
|
||||
* PIE and SSP are enabled by default, as is done on every major modern Linux
|
||||
distribution.
|
||||
* libssp is disabled and handed off to the libc (done by many modern Linux
|
||||
distributions). libssp in GCC is very broken and glibc-centric - it should
|
||||
really be handled by the libc, which is what most distributions do.
|
||||
* LTO now fully functions correctly, despite both the linker and the compiler
|
||||
being static binaries.

The original motivation from this patch from Alpine Linux:
|
||||
|
||||
Subject: [PATCH] Alpine musl package provides libssp_nonshared.a. We link to
|
||||
it unconditionally, as otherwise we get link failures if some objects are
|
||||
-fstack-protector built and final link happens with -fno-stack-protector.
|
||||
This seems to be the common case when bootstrapping gcc, the piepatches do
|
||||
not seem to fully fix the crosstoolchain and bootstrap sequence wrt.
|
||||
stack-protector flag usage.
|
||||
|
||||
Which matches precisely the problem when compiling GCC with --enable-bootstrap
|
||||
in live-bootstrap.
