Branch: CURRENT, Version: 20.1.8, Package name: llvm-20.1.8, Maintainer: pkgsrc-users

Low Level Virtual Machine (LLVM) is:

A compilation strategy designed to enable effective program optimization across
the entire lifetime of a program. LLVM supports effective optimization at
compile time, link-time (particularly interprocedural), run-time and offline
(i.e., after software is installed), while remaining transparent to developers
and maintaining compatibility with existing build scripts.

A virtual instruction set - LLVM is a low-level object code representation that
uses simple RISC-like instructions, but provides rich, language-independent,
type information and dataflow (SSA) information about operands. This combination
enables sophisticated transformations on object code, while remaining
light-weight enough to be attached to the executable. This combination is key to
allowing link-time, run-time, and offline transformations.

A compiler infrastructure - LLVM is also a collection of source code that
implements the language and compilation strategy. The primary components of the
LLVM infrastructure are the C & C++ front-end, a link-time optimization
framework with a growing set of global and interprocedural analyses and
transformations, static back-ends for the X86, X86-64, PowerPC 32/64, ARM,
Thumb, IA-64 and SPARC architectures, a back-end which emits portable C
code, and a Just-In-Time compiler for X86, X86-64, PowerPC 32/64 processors.

Log message:
llvm: use gcc 14 on NetBSD 9

Both base gcc (8) and gcc10 cause llvm to mis-compile lang/wasi-libc,
which is required for a Firefox build. With gcc14, I can successfully
build firefox128.

The GCC_REQD goes into version.mk, so that it also applies to clang
and LLVM-adjacent packages. It is also in buildlink3.mk, or Rust
will fail to build because libLLVM uses a different C++ ABI.

This is not really a fix but a mitigation. It is limited to NetBSD 9,
so there should be no breakage on other platforms.

Log message:
lang/llvm: On NetBSD/i386 9.x, force use of GCC >= 10.

Gcc8 which is otherwise used blows up with per-process VM
exhaustion, i.e. with memory allocation failure.
