There are 2 quotes that are relevant. One explains a relationship not explicitly in the wording that is explicit about --disable-boostrap . The other is more general (and not explicit about command line options) but that the --disable-boostrap fits in. First QUOTE ( specific to --disable-boostrap ) This should not be done unless you are building with GCC itself. The reason is only the C, C++ front-ends are supposed to be able to compile with a (non-GCC) C++11 compiler. END QUOTE In other words: all other stages/parts are allowed to do things that clang/libc++ does not provide compatibility for. Turns out that internal name-poisoning to validate some gcc internal scope-of-use criteria are an example of the issue that can make libc++'s lack of design for the poisoning a problem. Such has been hit in new contexts in lang/gcc14-devel porting. It was also involved in the older a4831f4933d0 ( "lang/gcc12 lang/gcc12-devel lang/gcc13 lang/gcc13-devel lang/gcc14-devel: fix build without bootstrap" ). The above QUOTE can make it messy to determine if one has hit a front-end problem vs. not for making upstream bugzilla submittals. If not viewed by GCC as a front-end issue but from/for code from other stages/parts, support for changing things may be unlikely. In lang/gcc* terms, if STANDARD_BOOTSTRAP works, effectively the response to a submittal may be saying: "so use STANDARD_BOOTSTRAP". The following quote is from: https://gcc.gnu.org/install/prerequisites.html and so is explicitly official GCC material: Second QUOTE ( more general than --disable-boostrap ) To build all languages in a cross-compiler or other configuration where 3-stage bootstrap is not performed, you need to start with an existing GCC binary (version 4.8.3 or later) because source code for language frontends other than C might use GCC extensions. END QUOTE (There is a missing /C++ in the wording. Also, not wording explicitly inicating which option syntaxes have which implications.) One has to read into that that the name-poisoning imposition of scope-of-use design rules is an example of a GCC extension, one that libc++ does not follow (i.e., does not support). Various parts of the code make no claim to support a context that does not follow the design rule. (The front-end's code must not impose the design rule for its build.) In general, gcc producing gcc has to be involved for some stages in order to be supported and those stages can use the scope-of-rule rule imposed by name poisoning, as an example. Ultimately these may lead to the need to avoiding --disable-bootstrap ever being a default for some lang/gcc* examples. A contrinbuting issue is getting support from upstream. Another could be how complicated things get as gcc progresses. === Mark Millard marklmi at yahoo.com From nobody Mon Feb 26 13:50:28 2024 X-Original-To: freebsd-toolchain@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4Tk27W6LNMz5BR71 for ;

The above QUOTE can make it messy to determine if = one has hit a

If not viewed by GCC as a front-end issue but from/for = code from

In lang/gcc* terms, if STANDARD_BOOTSTRAP works, = effectively the
response to a submittal may be saying: "so use = STANDARD_BOOTSTRAP".



The following quote is = from:

and = so is explicitly official GCC material:

Second QUOTE ( more = general than --disable-boostrap )
To build all languages in a = cross-compiler or other configuration where

END QUOTE

(There is a missing /C++ = in the wording. Also, not wording explicitly
inicating which option = syntaxes have which implications.)

One has to read into that that = the name-poisoning imposition of
scope-of-use design rules is an = example of a GCC extension, one
that libc++ does not follow (i.e., = does not support). Various
parts of the code make no claim to support = a context that does

and those stages can use the scope-of-rule rule imposed = by
name poisoning, as an = example.https://gcc.gnu.org/pipermail/gcc-patches/2023-September/631611.ht= ml


Ultimately these may lead to the need to avoiding = --disable-bootstrap
ever being a default for some lang/gcc* examples. = A contrinbuting
issue is getting support from upstream. Another could = be how
complicated things get as gcc progresses.

Thanks a lot Mark for = your analysis, both in this email and in the other
email thread.

I am proceeding to = slowly dump the possibility to build GCC ports without
bootstrap: indeed, = building lang/gcc14-devel port without bootstrap is broken
at the moment (which is = the starting poing of the whole discussion) and it will
not be fixed.
I am keeping this = possibility for older GCC versions for now: they build, they
are not broken, even = without bootstrap. If future updates break them too, I
will require bootstrap = for them too.
But starting from GCC 14 = ports, all GCC ports will require to select a bootstrap
option = (STANDARD_BOOTSTRAP being the default).

This = also means that I need to make some changes to my testing = environment...
I am = already working on it and I am fairly confident that I can find a = decent
solution.

Just last week I discovered that lldb is unable to resolve debug information for types defined in other shared libraries, so you really need to build with -glldb or -fstandalone-debug to get any support for e.g. standard library types ( https://github.com/llvm/llvm-project/issues/60994#issuecomment-1447337360). The downside is that the resulting binaries are bigger so it depends on how important lldb support is.

I'm not sure we've thought about it much, but gdb is almost certain= ly
the right default tuning since it's what most developers are accustom to.

I think there is also an argument to default to lldb tuning. Just= last week I discovered that lldb is unable to resolve debug information fo= r types defined in other shared libraries, so you really need to build with= -glldb or -fstandalone-debug to get any support for e.g. standard library = types (https://github.com/llvm/llvm-project/issues/60994#issueco= mment-1447337360).

HardenedBSD 14-STABLE and 15-CURRENT build all applications and libraries in base with thick LTO (-flto). (With one eexception on 15-CURRENT: libc--but that's related to some fallout related to recent libc/csu/libsys changes in FreeBSD, the goal is to re-enable LTO for libc soon.) The problem you'll find with building libraries in base with LTO is that those ports that use alternative toolchains might break--mainly if they link with static libraries (.a files) from base. gcc doesn't read/parse LLVM IR bitcode files. You might even see some issues with different versions of the same toolchain. For example, if llvm in base is at version 16, but the port requests llvm-from-ports version 15, then the port might not build. llvm's LTO ABI isn't forward compatible. The reason HardenedBSD builds base libs and apps with LTO is for future support of Cross-DSO CFI. I've worked on Cross-DSO CFI support slowly over the past few years, and there's still a long ways to go. Hopefully that helps.
