From 1765b0231029c0479ddcf5d54e8f4882c5feda94 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Wed, 27 Jun 2018 12:04:25 +0200 Subject: [PATCH] add support for --disable-gcov For some targets (in my case VxWorks 5.5), libgcov does not compile due to missing functions and macros such as getpid() and F_OK. Incidentally, gcc/Makefile.in already contains comments such as # Install gcov if it was compiled. but there is no logic in place to actually allow gcov to not be compiled. So add an option for disabling build and install of libgcov and the related host tools.
