* flag-o-matic.eclass: allow -fno-sanitize* optionsSergei Trofimovich2021-05-081-1/+3
| | | | | | | | | | We already allow -fsanitize* options. Sometimes it's useful to enable -fsanitize= globally and disable ir in a few ebuilds. The change allows passing -fno-sanitize=all an similar to achieve that effect. Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* eclass: [QA] Revert multiple meaningless doc changesMichał Górny2020-12-281-36/+0
| | | | | | | | | | | Revert multiple meaningless eclass documentation changes, notably adding a lot of placeholders and documenting implementation details. These changes were aimed at silencing (valid) documentation warnings without actually providing valuable documentation to the end users. While some of these changes were beneficial, it would take a lot of effort to review them all and the author is unwilling to fix his mistakes. Signed-off-by: Michał Górny <mgorny@gentoo.org>

* eclass/flag-o-matic.eclass: Add missing MIPS CPU errata flagsJoshua Kinard2020-03-281-1/+3
| | | | | | | | | | | | | Noticed during a glibc build for MIPS-III ISA that the -mfix-r4000 and -mfix-r4400 gcc flags got stripped off. These are needed to work around known CPU errata in R4000 and R4400 CPUs. In addition, also add the -mfix-rm7000 option (and it's -mno form) to fix errata in the PMC RM7000 CPU, and the -mr10k-cache-barrier to control the generation of cache barriers to work around the side-effects of R10000's speculative execution capabilities.

* flag-o-matic.eclass: add LDFLAGS testing against linkerSergei Trofimovich2019-12-241-14/+58
| | | | | | | | | | | | | | | | Before the change we tested only compiler driver (gcc flag parser) for LDFLAGS. This does not cover cases when we would really like to filter out unsupported linker flags like -Wl,--hash-style=gnu passed to non-ELF targets. The change adds test-flag-CCLD() helper to perform all of assembly, compilation and linking steps. Helper is used to filter LDFLAGS variable in strip-unsupported-flags().

| | | | | | | | | | | | | In bug #687198 Julian noticed that strip-unsupported-flags() filters out '-B' but not '/foo' in CFLAGS='-B /foo' and causes breakage.

* flag-o-matic.eclass: Strip LDFLAGS unsupported by the C compiler, #621274Michał Górny2017-08-251-0/+3
| | | | | | | | 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 Górny2017-08-251-1/+8
| | | | | | | | | | | | | | | | | | | 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: Replace unnecessary evalsMichał Górny2017-03-081-6/+5
| | | | | | | | | Replace the evals used to export variables with plain export calls. Bash expands variable references for exported variable name anyway, rendering the eval completely unnecessary. Replace the single eval used for indirect variable reference with the ${!...} substitution which serves that exact purpose in bash.

* proj/gentoo: Initial commitRobin H. Johnson2015-08-081-0/+673
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.
