[PATCH] D77786: [AArch64] Add v8.5 Branch Target Identification support.

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added inline comments.


================
Comment at: libunwind/src/assembly.h:46
 .Lfunc_begin0:
+#elif (defined(__arm64__) || defined(__aarch64__)) && defined(__ARM_FEATURE_BTI_DEFAULT)
+#define PPC64_OPD1  \
----------------
Just use `defined(__aarch64__)`. I deleted `__arm64__` in D77829


================
Comment at: libunwind/src/assembly.h:48
+#define PPC64_OPD1  \
+  .pushsection ".note.gnu.property", "a" SEPARATOR \
+  .balign 8 SEPARATOR \
----------------
I am worried that we may want to change the section type for .note.gnu.property
