+Subject: [PATCH] compiler-rt: Fix FLOAT16 feature detection
+
+CMAKE_TRY_COMPILE_TARGET_TYPE defaults to EXECUTABLE, which causes
+any feature detection code snippet without a main function to fail,
+so we need to make sure it gets explicitly set to STATIC_LIBRARY.

-Subject: [PATCH 5/5] [tsan] Refine fstat{,64} interceptors (#86625)
-
-In glibc versions before 2.33. `libc_nonshared.a` defines
-`__fxstat/__fxstat64` but there is no `fstat/fstat64`. glibc 2.33 added
-`fstat/fstat64` and obsoleted `__fxstat/__fxstat64`. Ports added after
-2.33 do not provide `__fxstat/__fxstat64`, so our `fstat/fstat64`
-interceptors using `__fxstat/__fxstat64` interceptors would lead to
-runtime failures on such ports (LoongArch and certain RISC-V ports).
-
-Similar to https://reviews.llvm.org/D118423, refine the conditions that
-we define fstat{,64} interceptors. `fstat` is supported by musl/*BSD
-while `fstat64` is glibc only.
-
-(cherry picked from commit d5224b73ccd09a6759759791f58426b6acd4a2e2)

+Subject: [PATCH] [hwasan][aarch64] Fix missing DT_AARCH64_BTI_PLT flag
+
+When building hwasan on aarch64, the DT_AARCH64_BTI_PLT flag is missing
+from libclang_rt.hwasan.so because some object files without
+DT_AARCH64_BTI_PLT are linked in the final DSO.
+These files are specific to riscv64 and x86_64, ending up with no
+aarch64 code in them.
+
+Avoid building and linking architecture-specific files unless the
+architecture is listed in HWASAN_SUPPORTED_ARCH.

+
+Start functions with BTI in order to identify the function as a valid
+branch target.
+Also add the BTI marker to tsan_rtl_aarch64.S.
+
+With this patch, libclang_rt.tsan.so can now be generated with
+DT_AARCH64_BTI_PLT when built with -mbranch-protection=standard.
