* flag-o-matic.eclass: Strip LDFLAGS unsupported by the C compiler, #621274Michał Górny2017-08-251-1/+1
| | | | | | | | Include LDFLAGS in the variables stripped by strip-unsupported-flags. The code reuses the current functions for testing CC, and so only remove LDFLAGS that are rejected by the C compiler and not the linker. This solves the case of bug #621274 where LDFLAGS contained GCC-specific -flto flag.
* flag-o-matic.eclass: test-flag-PROG, ignore unused args in clangMichał Górny2017-08-251-0/+5
| | | | | | | | | | | | | | | | | | | By default, clang considers unused arguments as error when -Werror is used. Since flag tests are performed without linking, this causes all tests for linker flags to fail inadvertently and all those flags are stripped as a result. While the correctness of passing unused flags is doubtful, silently stripping them in a few random packages is certainly not the solution to the problem, and also makes the results differ between gcc and clang. To account for that, use clang's -Qunused-arguments option to silence unused argument warnings. To avoid wasting time on testing the compiler, just try passing -Qunused-arguments every time a flag check fails. If clang is not used, the additional call will fail just the same as the previous one (either because of the original flag or because of -Qunused-arguments), so the result will be the same.
* flag-o-matic.eclass: Revert "Strip LDFLAGS unsupported by the C..."Michał Górny2017-08-111-1/+1
| | | | | | | The current logic strips too much, causing build failures. Revert it until we get it right. Bug: https://bugs.gentoo.org/627474

This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H.
