* toolchain-funcs.eclass: Remove outdated reference to tc-has-openmpPetr Vaněk2023-10-011-3/+1
| | | | | | | | | | | | tc-has-openmp function was deprecated in commit 9bc832c6d39b ("toolchain-funcs.eclass: deprecate tc-has-openmp") and later removed in commit eb970274d283 ("toolchain-funcs.eclass: remove tc-has-openmp"). Due to this, the reference to it in the tc-check-openmp function has become redundant and is therefore removed.

* toolchain-funcs.eclass: tc-enables-fortify-source: update for newer libcxxSam James2023-08-181-2/+2
| | | | | | | | Newer libcxx uses _LIBCPP_ENABLE_HARDENED_MODE instead of _LIBCPP_ENABLE_ASSERTIONS which is now deprecated. Bug: https://bugs.gentoo.org/912223 Signed-off-by: Sam James <sam@gentoo.org>
* toolchain-funcs.eclass: cleanup obsolete bits in tc-ld-force-bfdSam James2023-07-301-19/+0
| | | | | | | | | | | | I didn't want to drop this entirely in c26413ae8029f1557aae95b6f8744fc16671fa3b as I wanted to keep it to just fixing the error I'd made, but I don't see the point in keeping this now anyway - non-gcc/clang isn't a thing and if it is I'd hope they'd support -fuse-ld=bfd anyway. Plus it's an obvious approach if we need it for something else like forcing an alt linker that isn't bfd anyway, no need for having cruft remaining. Signed-off-by: Sam James <sam@gentoo.org>

| | | | | | | | | | | | It makes a bit more sense (although still a bit suspicious, wonder if should strip . as well, see c26413ae8029f1557aae95b6f8744fc16671fa3b and bug #911503 where we had 'ld.lld.bd') now with the comment in the right place.

| | | | | | | | | | | | As Zero_Chaos reported on IRC, the check we had wasn't good enough in systemd* (before we were able to remove it), as it wouldn't fire for e.g. -Os. While we could've changed it to fail safe (always unset, then set a lower F_S if possible), let's add a proper helper instead to the eclass.

| | | | | | | | | | | | We were setting CBUILD within econf_build but not CHOST. crossdev's /usr/share/config.site relies on both of these to decide whether to load configure overrides needed when cross-compiling. Using the wrong overrides leads to packages such as Python failing. Doing this also avoids the need to duplicate the --build and --host configure arguments.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 921cb9c10de4d237924a61a1c27f914dfb479a64 "toolchain-funcs.eclass: Update tc-is-softfloat for new ARM tuples" changed autodetection of mst 'arm*' targets from from 'no' to 'yes'. It is incorrect at least for bare-metal targets that tend to pass their taget defaults. Bug #666896 is one example example command: # crossdev -s1 \ --env 'EXTRA_ECONF="--with-multilib-list=rmprofile"' \ arm-none-eabi rmprofile one of special cases for gcc as it explicitky does not myx with any arch-specific options and --with-float=soft breaks it: Error: You cannot use any of --with-arch/cpu/fpu/float/mode with --with-multilib-list=rmprofile The immediate fix is to restore initial autodetection for bare-metal targets.

* toolchain-funcs.eclass: Update tc-is-softfloat for new ARM tuplesJames Le Cuirot2018-08-211-14/+60
| | | | | | | | | | | | | | | | | ARM tuples will change from armv7a-hardfloat-linux-gnueabi to armv7a-unknown-linux-gnueabihf or similar in the 17.0 profiles. The function already treated the latter as hardfloat but this commit will now treat ambiguous tuples such as arm-unknown-linux-gnueabi as softfloat rather than hardfloat. This brings Gentoo in line with most of the ARM Linux community. However, the function will now check existing toolchains to avoid breaking existing systems, if possible. This has been achieved by splitting the function in three, tc-detect-is-softfloat for checking existing toolchains, tc-tuple-is-softfloat for checking just the tuple, and the new tc-is-softfloat that calls the first two. The output from the first two could be compared to inform the user that they are not using a recommended tuplet.
* toolchain-funcs.eclass: tc-cpp-is-true function to simplify helpersJames Le Cuirot2018-08-211-28/+25
| | | | | CTARGET is used, if defined, otherwise CHOST. CHOST was previously assumed but this should not affect existing usage of these helpers.
* toolchain-funcs.eclass: New tc-getTARGET_CPP functionJames Le Cuirot2018-08-211-0/+11
| | | | | | | | | | | This returns the name of the C preprocessor for the toolchain being built if CTARGET is defined, or the toolchain being used otherwise. It is primarily intended to determine characteristics about an existing toolchain's target as these may differ from what the tuple suggests. It is not necessary to add the full set of tc-getTARGET_* helper functions as this is probably the only reason we would ever invoke a toolchain in the context of CTARGET.
* toolchain-funcs.eclass: fix tc-ld-disable-gold when using clangRahul Chaudhry2018-05-261-8/+22
| | | | | | | | | | | | | tc-ld-disable-gold checks gcc version to see if we have gcc-4.8+ The version check fails if clang is set as the compiler. $ clang -E -P - <<<"__GNUC__ __GNUC_MINOR__ __GNUC_PATCHLEVEL__" 4 2 1 i.e. clang returns a gcc version of 4.2.1 This results in incorrectly adding -B ... to LDFLAGS, when clang supports "-fuse-ld" just fine. Support for "-fuse-ld" first appeared in clang-3.5, so check clang version and use the flag if supported.
