bootstrap/llvm16/dwarf-info.patch

+Author: A. Wilcox <awilfox@adelielinux.org>
+
+This isn't the proper fix, but debugging the LLVM formatter is a bit
+above my paygrade at the moment.
+
+The issue shows up in the DWARF X86 test on ppc and armv7:
+
+error: Simplified template DW_AT_name could not be reconstituted:
+         original: f3<char, '\x00', '\x01', '\x06', '\a', '\r', '\x0e', '\x1f', ' ', '!', '\x7f', '\x80'>
+    reconstituted: f3<char, '\x00', '\x00', '\x00', '\a', '\r', '\x00', '\x00', ' ', '!', '\x00', '\x00'>
+
+With this patch, this error does not occur.  Debugging shows that the
+llvm::format overload called in the error case is <long long>, so I
+think it is having an issue converting a 64-bit value on platforms
+where char is default-unsigned.
+
+(pmmx does not show this issue, and has signed char.)

+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.

bootstrap/llvm18/dwarf-info.patch

+Author: A. Wilcox <awilfox@adelielinux.org>
+
+This isn't the proper fix, but debugging the LLVM formatter is a bit
+above my paygrade at the moment.
+
+The issue shows up in the DWARF X86 test on ppc and armv7:
+
+error: Simplified template DW_AT_name could not be reconstituted:
+         original: f3<char, '\x00', '\x01', '\x06', '\a', '\r', '\x0e', '\x1f', ' ', '!', '\x7f', '\x80'>
+    reconstituted: f3<char, '\x00', '\x00', '\x00', '\a', '\r', '\x00', '\x00', ' ', '!', '\x00', '\x00'>
+
+With this patch, this error does not occur.  Debugging shows that the
+llvm::format overload called in the error case is <long long>, so I
+think it is having an issue converting a 64-bit value on platforms
+where char is default-unsigned.
+
+(pmmx does not show this issue, and has signed char.)

bootstrap/llvm18/hexagon.patch

+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.

bootstrap/llvm18/llvm-fix-build-with-musl-libc.patch

+From 5c571082fdaf61f6df19d9b7137dc26d71334058 Mon Sep 17 00:00:00 2001
+From: Natanael Copa <ncopa@alpinelinux.org>
+Date: Thu, 18 Feb 2016 10:33:04 +0100
+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.
