+Subject: [PATCH] PR119376: Disable clang musttail
+
+There are multiple reports (see PR 119376) now where semantic differences
+in the gcc musttail implementation break existing programs written for the clang
+variant.
+
+Even though that can be all hopefully fixed eventually,
+for the gcc 15 release it seems safer to disable clang::musttail,
+and only keep gnu::musttail.
+
+That means that programs that use __has_c_attribute to check for
+clang::musttail must opt-in explicitly.
+

+Subject: [PATCH] i386: Fix up combination of -2 r<<= (x & 7) into btr
+ [PR119428]
+
+The following patch is miscompiled from r15-8478 but latently already
+since my r11-5756 and r11-6631 changes.
+The r11-5756 change was
+https://gcc.gnu.org/pipermail/gcc-patches/2020-December/561164.html
+which changed the splitters to immediately throw away the masking.
+And the r11-6631 change was an optimization to recognize
+(set (zero_extract:HI (...) (const_int 1) (...)) (const_int 1)
+as btr.
+
+The problem is their interaction. x86 is not a SHIFT_COUNT_TRUNCATED
+target, so the masking needs to be explicit in the IL.
+And combine.cc (make_field_assignment) has since 1992 optimizations
+which try to optimize x &= (-2 r<< y) into zero_extract (x) = 0.
+Now, such an optimization is fine if y has not been masked or if the
+chosen zero_extract has the same mode as the rotate (or it recognizes
+something with a left shift too). IMHO such optimization is invalid
+for SHIFT_COUNT_TRUNCATED targets because we explicitly say that
+the masking of the shift/rotate counts are redundant there and don't
+need to be part of the IL (I have a patch for that, but because it
+is just latent, I'm not sure it needs to be posted for gcc 15 (and
+also am not sure if it should punt or add operand masking just in case)).
+x86 is not SHIFT_COUNT_TRUNCATED though and so even fixing combine
+not to do that for SHIFT_COUNT_TRUNCATED targets doesn't help, and we don't
+have QImode insv, so it is optimized into HImode insertions. Now,
+if the y in x &= (-2 r<< y) wasn't masked in any way, turning it into
+HImode btr is just fine, but if it was x &= (-2 r<< (y & 7)) and we just
+decided to throw away the masking, using btr changes the behavior on it
+and causes e2fsprogs and sqlite miscompilations.
+
+So IMHO on !SHIFT_COUNT_TRUNCATED targets, we need to keep the maskings
+explicit in the IL, either at least for the duration of the combine pass
+as does the following patch (where combine is the only known pass to have
+such transformation), or even keep it until final pass in case there are
+some later optimizations that would also need to know whether there was
+explicit masking or not and with what mask. The latter change would be
+much larger.
+
+The following patch just reverts the r11-5756 change and adds a testcase.
