+From 37605662a99bd0815e2f2e452eb6ab1ce53ecffd Mon Sep 17 00:00:00 2001
+From: "A. Wilcox" <AWilcox@Wilcox-Tech.com>
+Date: Mon, 30 May 2022 02:51:34 -0500
+Subject: [PATCH] [Hexagon][Tests] Fix tests on Linux/musl
+
+When running on a host system using musl, the target triple is defined
+as hexagon-unknown-linux-musl by default.  The Linux ABI differs from
+the non-Linux one with varargs, so this causes the tests to fail.
+
+Closes BZ49592, PR48936.

+Subject: [PATCH 2/3] Fix build with musl libc
+
+On musl libc the fopen64 and fopen are the same thing, but for
+compatibility they have a `#define fopen64 fopen`. Same applies for
+fseek64, fstat64, fstatvfs64, ftello64, lstat64, stat64 and tmpfile64.

+Subject: [PATCH] Add support for powerpc64-*-linux-musl targets
+
+This patch ensures that 64-bit PowerPC musl targets use ELFv2 ABI on both
+endians.  It additionally adds a test that big endian PPC64 uses ELFv2 on
+musl.

+Subject: [PATCH] SCC: Allow ReplaceNode to safely support insertion
+
+If scc_iterator::ReplaceNode is inserting a new entry in the map,
+rather than replacing an existing entry, the possibility of growing
+the map could cause a failure.  This change safely implements the
+insertion.
