sys-libs/musl: Filter LTO After discussing my bug with dalias on #musl I was informed that LTO has a negative impact on Musl so fixing the issue I highlight rather than filtering wouldn't be the desired outcome for the user. This will also help crossdev users as a bonus as -flto applies to the crosstoolchain and can be hard to spot at first. Chat log to comfirm: immolo: I ran into the -flto issue while testing musl built with lto and the only thing I can find on it was a workaround in 2015. immolo: My question though is it even worth having lto enabled on musl in the first place as every distro just seems to filter it so there must be a reason dalias: not only is it not worth it. it's negative value dalias: makes musl larger and slower dalias: if you wanted libc.a to get LTO'd into static programs, that might have some value dalias: but LTO on libc.so is worse than worthless Closes: https://bugs.gentoo.org/877343 Thanks-to: dalias Signed-off-by: Ian Jordan <immoloism <AT> gmail.com> Closes: https://github.com/gentoo/gentoo/pull/27824 Signed-off-by: Sam James <sam <AT> gentoo.org> sys-libs/musl/musl-1.2.2-r8.ebuild | 1 + sys-libs/musl/musl-1.2.3-r4.ebuild | 1 + sys-libs/musl/musl-1.2.3.ebuild | 1 + sys-libs/musl/musl-9999.ebuild | 1 + 4 files changed, 4 insertions(+) diff --git a/sys-libs/musl/musl-1.2.2-r8.ebuild b/sys-libs/musl/musl-1.2.2-r8.ebuild index a7b1acd0c36c..2c16357eb55f 100644 --- a/sys-libs/musl/musl-1.2.2-r8.ebuild +++ b/sys-libs/musl/musl-1.2.2-r8.ebuild @@ -88,6 +88,7 @@ src_prepare() { } src_configure() { + filter-lto # bug #877343 tc-getCC ${CTARGET} just_headers && export CC=true diff --git a/sys-libs/musl/musl-1.2.3-r4.ebuild b/sys-libs/musl/musl-1.2.3-r4.ebuild index 1d60464d46a4..6f2527e85a39 100644 --- a/sys-libs/musl/musl-1.2.3-r4.ebuild +++ b/sys-libs/musl/musl-1.2.3-r4.ebuild @@ -104,6 +104,7 @@ src_prepare() { } src_configure() { + filter-lto # bug #877343 tc-getCC ${CTARGET} just_headers && export CC=true diff --git a/sys-libs/musl/musl-1.2.3.ebuild b/sys-libs/musl/musl-1.2.3.ebuild index a7b1acd0c36c..2c16357eb55f 100644 --- a/sys-libs/musl/musl-1.2.3.ebuild +++ b/sys-libs/musl/musl-1.2.3.ebuild @@ -88,6 +88,7 @@ src_prepare() { } src_configure() { + filter-lto # bug #877343 tc-getCC ${CTARGET} just_headers && export CC=true diff --git a/sys-libs/musl/musl-9999.ebuild b/sys-libs/musl/musl-9999.ebuild index 1d60464d46a4..6f2527e85a39 100644 --- a/sys-libs/musl/musl-9999.ebuild +++ b/sys-libs/musl/musl-9999.ebuild @@ -104,6 +104,7 @@ src_prepare() { } src_configure() { + filter-lto # bug #877343 tc-getCC ${CTARGET} just_headers && export CC=true
