From 8d0ef282099ee0681222631bfb6421e28a177906 Mon Sep 17 00:00:00 2001 From: Olivier Hainque Date: Fri, 21 Sep 2018 13:05:19 +0000 Subject: [PATCH] Cleanup handling of libgcc and libc_internal for VxWorks 2018-09-21 Olivier Hainque * config/vxworks.h (VXWORKS_LIBGCC_SPEC): Remove -lc_internal. Merge block comment with the one ahead of VXWORKS_LIBS_RTP. Then: (VXWORKS_LIBS_RTP): Minor reordering.
