From cf597595ae72945085a37d94689f250765888264 Mon Sep 17 00:00:00 2001 From: Nicholas Nethercote Date: Wed, 29 Nov 2023 15:08:43 +1100 Subject: [PATCH] Rearrange `default_configuration` and `CheckCfg::fill_well_known`. There are comments saying these two functions should be kept in sync, but they have very different structures, process symbols in different orders, and there are some inconsistencies. This commit reorders them so they're both mostly processing symbols in alphabetical order, which makes cross-checking them a lot easier. The commit also adds some macros to factor out repetitive code patterns. Plus it adds `sanitizer_cfi_normalize_{integers,pointers}` to `fill_well_known`, which were missing. The commit also moves the handling of `sym::test` out of `build_configuration` into `default_configuration`, where all the other symbols are handled. --- compiler/rustc_session/src/config.rs | 329 ++++++++++-------- tests/ui/check-cfg/allow-same-level.stderr | 2 +- tests/ui/check-cfg/compact-names.stderr | 2 +- .../exhaustive-names-values.empty_cfg.stderr | 2 +- ...ive-names-values.empty_names_values.stderr | 2 +- .../exhaustive-names-values.feature.stderr | 2 +- .../exhaustive-names-values.full.stderr | 2 +- .../exhaustive-names.empty_names.stderr | 2 +- .../exhaustive-names.exhaustive_names.stderr | 2 +- tests/ui/check-cfg/mix.cfg.stderr | 2 +- tests/ui/check-cfg/mix.names_values.stderr | 2 +- tests/ui/check-cfg/stmt-no-ice.stderr | 2 +- tests/ui/check-cfg/well-known-names.stderr | 2 +- 13 files changed, 187 insertions(+), 166 deletions(-) diff --git a/compiler/rustc_session/src/config.rs b/compiler/rustc_session/src/config.rs index e694e150b314b..c9dcf1d2b21cb 100644 --- a/compiler/rustc_session/src/config.rs +++ b/compiler/rustc_session/src/config.rs @@ -1246,46 +1246,85 @@ pub const fn default_lib_output() -> CrateType { } fn default_configuration(sess: &Session) -> Cfg { -
