Homebrew has GCC 9, which offers flawless development experience, at least
up to quite advanced applications. There of course could be corner cases in
ABI, exceptions handling, etc., which I however never came across myself on
MacOS. Thus, discussing gcc 4.2 seems to be highly nonsensical these
Qt4 is an old release (the current one is almost Qt6). A newer compiler is
usually backward-compatible with older codes. So you should be able to
compile Qt4 on Ubuntu 20.04 with system-provided GCC right away.

Maybe the best form of question is: Could the Overseer be so kind to
release the dump of the original old mailing list on any free public file
server?

Trying to plan memory consumption ahead-of-work contradicts with the nature
of the graph traversal. Estimation may work very well for something simple
like linear or log-linear behavior. But many compiler algorithms are known
to be polynomial or exponential (or even worse in case of bugs). So,
This issue is well-known in research/scientific software. The problem of
compiler hang or RAM overconsumption is actually not about the routine
size, but about too complicated control flow. When optimizing, the compiler
traverses the control flow graph, which may have the misfortune to explode
in
Linear equation solvers is not the scope of . There are many
packages serving this particular purpose, try looking into e.g. LAPACK.

First of, "error opening libc.a" message looks highly unusual. It's not the
way ld typically complains about a missing library or wrong architecture.
More likely, here it is rather some gcc-internal lib.a to be deployed in
some special way, but was missing.
I would try two things:
1) Re-iterate
esponds to (at least) "-O3
-ffast-math -march=native" of GCC. Omitting "-ffast-math" obviously
introduces significant performance gap.

Hi Alec,
Nvidia (IIRC, this was like a year ago though) don't even give out
the instruction set for their GPUs
I understand you don't want to bound to PTX virtual assembler, as it
conversion to GPU native assembler relies on proprietary component.

Dear all,
I'm trying to build a GCC toolchain (4.8-20130912 snapshot) targeting

GCC compiled with this change is used to recompile GCC itself. LTO is
not used, so I did not expect any problem. However, GCC built with
this change randomly segfaults or corrupts the output assembly files.

There was no such issue with May' gcc snapshot and binutils-2.22. Is it

FWIW, we also needed to perform multiple invocations of toplev_main from
a single execution of GCC frontend, which seems to be quite similar. The
dirty dirty hack is to save the backup the content of .data and .bss
symbols with ELF API before the first call to toplev_main and reset them
to backup
and very fragile.
That's why I'm saying FWIW, meaning it might be useful for some
internal transitioning during your very useful effort.
