+Subject: [PATCH] __warn_references: tweak assembly for "gnu.warning" section
+
+On some targets ';' (like hppa) is treated as a comment
+in assembly files. This occasionally causes the following
+assembly failures:
+
+```
+Error: can't resolve `.gnu.warning.EVP_DecryptFinal'
+{.gnu.warning.EVP_DecryptFinal section} - `.Ltext0' {.text section}
+```
+
+Note how branch (or other reference) attempts to cross the
+boundary across two section types: '.text' and '.gnu.warning'.
+
+Tobias Ulmer notes that openbsd already uses newlines
+for similar macro:
+
+https://github.com/openbsd/src/blob/master/sys/arch/hppa/include/cdefs.h
+
+This change switches from ';' to newline as well.
+Tested on hppa2.0 and x86_64.
