This adds 3 new options to patch order:
* bundled + bundled_exp
* bundled + bundled_exp + local
* local + bundled + bundled_exp
The path for bundled experimental patches is: ${CT_LIB_DIR}/packages/${pkg_dir}/experimental
and patches that are still being reviewed, but not yet applied upstream
may be toggled with ENABLE_EXPERIMENTAL_BUNDLED_PATCHES.
Also fix modelines for editors on bootstrap and scripts/functions, and
fix mix whitespace in scripts/functions.
Closes: #1916

# multilib-os (--print-multi-os-directory)
|
|
# as the gcc library and gcc sysroot library paths, respectively.
|

# For example, on x86_64:
|
|
# multilib: -m32=32 -m64=.
|
|
# multilib-os: -m32=../lib -m64=../lib64
|
|
# Moreover, while some multilibs can coexist in the same sysroot (e.g.
|
|
# on x86), some have a "sysroot suffix" to separate incompatible variants.
|
|
# Such sysroot suffixes combine with multilib-os directories, e.g.
|
|
# on sh4 with -m4a multilib, the search order in sysroot is (dropping some
|
|
# directories for brevity:
|
|
# <sysroot>/m4a/lib/m4a/
|
|
# <sysroot>/m4a/usr/lib/m4a/
|
|
# <sysroot>/m4a/lib/
|
|
# <sysroot>/m4a/usr/lib/
|
|
# The problem is that while GCC itself is aware of these subtleties, the
|
|
# binutils (notably, ld) it invokes under the hood are not. For example,
|
|
# if a shared library libfoo.so.1 requires libbar.so.1, ld will only search
|
|
# for libbar.so.1 in <sysroot>/m4a/usr/lib, but not in <sysroot>/m4a/usr/lib/m4a.
|
|
# In other words, 'gcc -lfoo -lbar' will work for both the default and -m4a
|
|
# cases, and 'gcc -lfoo' will work for the default, but not for -m4a. To
|
|
# address this, we first try to determine if the sysroot alone makes the
|
|
# configuration sufficiently unique. If there are no multilibs within the
|
|
# same suffixed sysroot, we can drop the multi_os_dir and both gcc and ld
|
|
# will work. If not, we'll supply both multi_root/multi_os_dir (which will
|
|
# likely break later, e.g. while building final GCC with C++ support). But,
|
|
# we've done all we can.
|
