This removes workarounds for packages which are not present in the portage tree. It also updates the names of some packages which have been renamed. This is based on the upstream issue referenced below. Refs: InBetweenNames#859 Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
This removes the workarounds verified by neeshy to be unnecessary. See neeshy's comments reference in the below issue for more context. Refs: InBetweenNames#883 Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
The GentooLTO project has not gone through the effort of testing all of the workarounds it's accumulated over the years. This commit renames all of the .cflags files to be prefixed with untested- so that users know that they are not tested and may not be needed. It also adds a new version of the ltoize rebuild (0.10.0) that uses the new files. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
This recreates the original package.cflags files to hold workarounds which have been tested and deemed safe and necessary. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
This comments all untested workarounds. This will make it easier to see which are needed and incrementatlly enable them. Once tested, they can be moved to the un-prefixed package.cflags files. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
This updated the make.conf.lto file to enable the pgo and lto USE flags by default. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
This makes the override-flagomatic flag enabled in the ebuild by default, without changing the default behavior. This was done by adding LTO_ENABLE_FLAGOMATIC=yes to make.conf.lto. This allows the user to now use the flag-o-matic.conf file to disable flagomatic instead of using it to enable it. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
sys-devel/binutils handles its own LTO, so we need to disable the flags we add ourselves for it. Graphite and ipa-pta are tested to work, but flag-o-matic needs disabled for them to be applied. devirtualize-at-ltrans breaks the tests. no-semantic-interposition breaks the tests.

The symlink was incorrectly named wflag-o-matic.conf. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>

No isues were encountered when building this without the workarounds. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
No issues were encountered building this without workarounds. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
The no-common workarounds were primarily needed for GCC 9. Reviewing the GentooLTO issue tracker, and GentooLTO#484 in particular, it seems that GCC 10 and binutils 2.34 have resolved the issues. This commit removes the no-common workarounds and the keep-nocommon USE flag. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
It appears that the tls-dialect setting in GCC has very little testing and is not used very much. This removes the workarounds for it and I'll not be supporting it in the future. RefS: https://www.mail-archive.com/gcc-patches@gcc.gnu.org/msg170586.html Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
This removes the prelink support from this project. It seems to have few users left and is not worth the effort to maintain. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
This removes the support and workarounds for the no-plt flag. Usage of the flag interferes with lazy binding and doesn't seem to be worth the effort to maintain. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
As of Python 3.12, the gentoo repo supports both an LTO and PGO flag. Maintaining a distinct python package in this repo is no longer necessary. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
The packages removed in this commit are no longer present in the gentoo tree, so the workarounds are no longer needed. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
This adds a header to each untested file that lists the number of workarounds in it which have yet to be tested. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>

This enables the no-semantic-interposition workaround for umockdev now that it has been tested as still being necessary. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
app-crypt/gcr has been tested to work with LTO but semantic interposition must be disable. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>

This updates the counts of untested workarounds in the file headers. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
This adds the below flags to the LTO_WARNING_FLAGS variable and adds it to CFLAGS by default. These flags are from the Gentoo wiki. If a package fails to compile with these flags, LTO should not be used. - -Werror=odr - -Werror=lto-type-mismatch - -Werror=strict-aliasing Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>
This has been tested to be incompatible with LTO. Signed-off-by: Jaremy Hatler <hatler.jaremy@gmail.com>

This cleans up the workarounds which have accumulated over time.
The work of neeshy in InBetweenNames#883 and the details of InBetweenNames#859 were incorporated into this PR.
Then, all of the remaining workarounds were moved to package.cflags files prefixed with untested- and commented. A new version of ltoize (0.10.0) was created which installed the prefixed and non-prefixed files.
From here, this PR will need incrementally updated as things are tested. Commented workaround which are found to be unneeded should be delete. Workarounds still needed should be tested locally, and then moved to the unprefixed files. This workflow will allow the untested- files to act as a backlog of what still needs tested.
