Bug 923066 – dev-lang/rust-1.74.1[llvm_targets_ARC] fails to compile: The target `ARC' is experimental and must be passed via LLVM_EXPERIMENTAL_TARGETS_TO_BUILD

• Status: CONFIRMED
• Product: Gentoo Linux

[Description matoro 2024-01-28 03:23:20 UTC]

This is an issue because USE=test requires all LLVM_TARGETS to be enabled, therefore it's impossible to build dev-lang/rust with USE=test.

CMake Error at CMakeLists.txt:925 (message):
  The target `ARC' is experimental and must be passed via
  LLVM_EXPERIMENTAL_TARGETS_TO_BUILD.

# causes double bootstrap
RESTRICT="test"

so not a blocker
