<pre class="commit-message" style='white-space: pre-wrap; display: block; font-size: 14px; color: #333238; position: relative; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; word-break: break-all; word-wrap: break-word; background-color: #fbfafd; border-radius: 2px; margin: 0; padding: 8px 12px; border: 1px solid #dcdcde;'>Transform some StgRhsClosure into StgRhsCon after unarisation (#25166)
Before unarisation we may have code like:
Test.foo :: Test.D
[GblId, Unf=OtherCon []] =
\u []
case (# |_| #) [GHC.Types.(##)] of sat_sAw [Occ=Once1] {
__DEFAULT -> Test.D [GHC.Types.True sat_sAw];
};
After unarisation we get:
Test.foo :: Test.D
[GblId, Unf=OtherCon []] =
{} \u [] Test.D [GHC.Types.True 2#];
Notice that it's still an Updatable closure for no reason anymore. This
patch transforms appropriate StgRhsClosures into StgRhsCons after
unarisation, allowing these closures to be statically allocated. Now we
get the expected:
Test.foo :: Test.D
[GblId, Unf=OtherCon []] =
Test.D! [GHC.Types.True 2#];
Fix #25166
To avoid duplicating code, this patch refactors the mk(Top)StgRhs
functions and put them in a GHC.Stg.Make module alongside the new
mk(Top)StgRhsCon_maybe functions.
