+Subject: [PATCH] [CMake][ELF] Link libLLVM.so and libclang-cpp.so with
+ -Bsymbolic-functions
+
+llvm-dev message: https://lists.llvm.org/pipermail/llvm-dev/2021-May/150465.html
+
+In an ELF shared object, a default visibility defined symbol is preemptible by
+default. This creates some missed optimization opportunities.
+-Bsymbolic-functions is more aggressive than our current -fvisibility-inlines-hidden
+(present since 2012) as it applies to all function definitions. It can
+
+* avoid PLT for cross-TU function calls && reduce dynamic symbol lookup
+* reduce dynamic symbol lookup for taking function addresses and optimize out GOT/TOC on x86-64/ppc64
+
+In a -DLLVM_TARGETS_TO_BUILD=X86 build, the number of JUMP_SLOT decreases from 12716 to 1628, and the number of GLOB_DAT decreases from 1918 to 1313
+The built clang with `-DLLVM_LINK_LLVM_DYLIB=on -DCLANG_LINK_CLANG_DYLIB=on` is significantly faster.
+See the Linux kernel build result https://bugs.archlinux.org/task/70697
+
+Note: the performance of -fno-semantic-interposition -Bsymbolic-functions
+libLLVM.so and libclang-cpp.so is close to a PIE binary linking against
+`libLLVM*.a` and `libclang*.a`. When the host compiler is Clang,
+-Bsymbolic-functions is the major contributor. On x86-64 (with GOTPCRELX) and
+ppc64 ELFv2, the GOT/TOC relocations can be optimized.
+
+Some implication:
+
+Interposing a subset of functions is no longer supported.
+(This is fragile on ELF and unsupported on Mach-O at all. For Mach-O we don't
+use `ld -interpose` or `-flat_namespace`)
+
+Compiling a program which takes the address of any LLVM function with
+`{gcc,clang} -fno-pic` and expects the address to equal to the address taken
+from libLLVM.so or libclang-cpp.so is unsupported. I am fairly confident that
+llvm-project shouldn't have different behaviors depending on such pointer
+equality (as we've been using -fvisibility-inlines-hidden which applies to
+inline functions for a long time), but if we accidentally do, users should be
+aware that they should not make assumption on pointer equality in `-fno-pic`
+mode.
+

+Subject: [PATCH] Twist shuffle mask when fold HOP(SHUFFLE(X,Y),SHUFFLE(X,Y))
+ -> SHUFFLE(HOP(X,Y))
+
+This patch fixes PR50823.
+
+The shuffle mask should be twisted twice before gotten the correct one due to the difference between inner HOP and outer.
