+Subject: [PATCH] [sanitizer_common] Fix build on ppc64+musl
+
+In powerpc64-unknown-linux-musl, signal.h does not include asm/ptrace.h,
+which causes "member access into incomplete type 'struct pt_regs'" errors.
+Include the header explicitly to fix this.
+
+Also in sanitizer_linux_libcdep.cpp, there is a usage of
+TlsPreTcbSize which is not defined in such a platform.
+Guard the branch with macro.

+Subject: [PATCH] tree-sra: Avoid total SRA if there are incompat. aggregate
+ accesses  (PR119085)
+
+We currently use the types encountered in the function body and not in
+type declaration to perform total scalarization.  Bug PR 119085
+uncovered that we miss a check that when the same data is accessed
+with aggregate types that those are actually compatible.  Without it,
+we can base total scalarization on a type that does not "cover" all
+live data in a different part of the function.  This patch adds the
+check.

-Subject: [PATCH] tree-sra: Avoid total SRA if there are incompat. aggregate
- accesses  (PR119085)
-
-We currently use the types encountered in the function body and not in
-type declaration to perform total scalarization.  Bug PR 119085
-uncovered that we miss a check that when the same data is accessed
-with aggregate types that those are actually compatible.  Without it,
-we can base total scalarization on a type that does not "cover" all
-live data in a different part of the function.  This patch adds the
-check.

-Subject: [PATCH] [sanitizer_common] Fix build on ppc64+musl
-
-In powerpc64-unknown-linux-musl, signal.h does not include asm/ptrace.h,
-which causes "member access into incomplete type 'struct pt_regs'" errors.
-Include the header explicitly to fix this.
-
-Also in sanitizer_linux_libcdep.cpp, there is a usage of
-TlsPreTcbSize which is not defined in such a platform.
-Guard the branch with macro.
