+Subject: [PATCH] libtool: Check for static libs for internal compiler
|
|
|
+ libraries
|
|
|
+
|
|
|
+Libtool checks only for libraries linked as -l* when trying to
|
|
|
+find internal compiler libraries. Clang, however uses the absolute
|
|
|
+path to link its internal libraries e.g. compiler_rt. This patch
|
|
|
+handles clang's statically linked libraries when finding internal
|
|
|
+compiler libraries.
