Using llvm-objdump I found warning if file was
compiled using riscv-gcc. Examples:
warning: failed to find source riscv-glibc/csu/elf-init.c
It concerned with compilation glibc with
debug info that is unnecessary operation. If user want to have debug info, than it's easy to pass -g.
This option wasn't touched more than 7 years...
This could help multi-lib testing, but the price is slightly increase
the testing time since it will need to extract ELF attribute from binary
before running qemu.
But I think the cost is acceptable compare to make build system more
complicate, and actually we already use this approach in our internal stuffs
for years.
There is no $(NEWLIB_TUPLE)-gcc in install directory
during cross-compilation process. For example,
to compile for Windows, we has to have riscv64-unknown-elf-gcc
in our PATH and we has to use it with print-multi-lib
to find multilib configuration, because install
folder contains only .exe files (can not be executed)
This bugfix is to check: whether compiler we already
have for host - in the install directory or in the PATH.
There is no way to pass extra flags to gcc though
riscv-gnu-toolchain Makefile.
This is neccesary for me, because I has to rewrite gmp,
isl, mpfr, mpc folders in source of gcc project. Moreover,
I don't want to rebuild them with gcc.
Also I think, the opportunity to pass extra flags will be
convenient for many development purposes.
We have this feature for all other packages.
It is particularly useful to avoid pointless internet downloads
for automatic builds.

glibc 2.37 has been released on February 1st, 2023.
We still use 2.33 in this repo.
Let's make a huge step forward to the latest upstream release.

This patch contains three minor updates:
1. Added texinfo to OS X dependency package
2. Brew tap discoteq/discoteq is no longer required to install the flock
3. Added tip in "Installation (Newlib)" to keep similar to the description
in "Installation (Linux)" and fixed a typo.

https://github.com/riscv-collab/riscv-gnu-toolchain/pull/1167 has found
some bug, and I realized the testing of march-to-cpu-opt is...not well,
so spend some time to improve that a little bit, it's not complete testing,
but at least it's a start :P
- We don't set correct qemu option for zdinx/zfinx/zhinx, this patch is
fixing the march-to-cpu-opt, which is a script translate -march string
to qemu options.
