ignore failing cross-compiled run-make tests `run-make-fulldeps` is never cross-compiled, so a lot of these tests never accounted for --target. Ignore them when cross-compiling for now. 2023-03-30 08:46:31 -05:00			`# ignore-cross-compile`
Diagnose missing includes in run-make tests 2022-08-23 00:00:00 +00:00			`include ../tools.mk`
use ignore directives for run-make tests This makes the tests easier to read, and makes it possible to tell which tests aren't being run on the host platform. Fixes #56704. 2019-01-06 16:27:57 -05:00

rustc: filter out empty linker args This is inspired by a mystifying linker failure when using `pkg-config` to generate the linker args: `pkg-config` produces output that ends in a space, thus resulting in an empty linker argument. Also added some updates to the concerning error messages that helped spotting this bug. 2013-12-01 11:08:46 +01:00			`# Notice the space in the end, this emulates the output of pkg-config`
Consolidate codegen-related compiler flags Move them all behind a new -C switch. This migrates some -Z flags and some top-level flags behind this -C codegen option. The -C flag takes values of the form "-C name=value" where the "=value" is optional for some flags. Flags affected: * --llvm-args => -C llvm-args * --passes => -C passes * --ar => -C ar * --linker => -C linker * --link-args => -C link-args * --target-cpu => -C target-cpu * --target-feature => -C target-fature * --android-cross-path => -C android-cross-path * --save-temps => -C save-temps * --no-rpath => -C no-rpath * -Z no-prepopulate => -C no-prepopulate-passes * -Z no-vectorize-loops => -C no-vectorize-loops * -Z no-vectorize-slp => -C no-vectorize-slp * -Z soft-float => -C soft-float * -Z gen-crate-map => -C gen-crate-map * -Z prefer-dynamic => -C prefer-dynamic * -Z no-integrated-as => -C no-integrated-as As a bonus, this also promotes the -Z extra-debug-info flag to a first class -g or --debuginfo flag. * -Z debug-info => removed * -Z extra-debug-info => -g or --debuginfo Closes #9770 Closes #12000 2014-02-06 19:57:09 -08:00			`RUSTC_FLAGS = -C link-args="-lc "`
