Hello,
looking at the changes for configuration in gcc 9.1, I noticed:
1) New configure options
OTOOL/OTOOL_FOR_TARGET: Which I assume from google is the Darwin ldd
replacement
GDC_FOR_TARGET: Which with a bit of guess work I assume is the
Gnu_D_Compiler
Is this stuff documented anywhere?
2) D language documentation
Also looking at the D documentation it appears missing in action:
No manual here: https://gcc.gnu.org/onlinedocs/
and the release notes just say: "Support for the D programming language
has been added to GCC, implementing version 2.076 of the language and
run-time library."
If this stuff is documented elsewhere a link to said documentation would
be useful.
3) Stdlibc++
Release notes reference parallel algorithms requiring TBB 2018 or newer,
again guess work suggests this is Thread Building Blocks. It would be
nice to explicitly say that, and provide links to implementations.
How is TBB detected and selected? I didn't see any configure switches
relating to this either in the toplevel configure or stdc++ configure
files. Can it be built in tree etc?
Also while TBB may not be a prerequisite should it be at least
documented on that page: https://gcc.gnu.org/install/prerequisites.html
(or somewhere)
The TBB release notes (written by Intel) seem to limit things to Intel
or compatible processors, wikipedia suggests a wider range (sparc?,
powerpc). Is ARM supported? Again it would be nice to document what
range of systems this can work on.
Thanks
Andrew
