From d31415ba1989c3d51c536fbba6a976b527213e44 Mon Sep 17 00:00:00 2001 From: James Greenhalgh Date: Mon, 3 Jul 2017 14:32:30 +0000 Subject: [PATCH] Andrew pointed out that I did not document the new architecture extension flag I added for the RcPc extension. Andrew pointed out that I did not document the new architecture extension flag I added for the RcPc extension. This was intentional, as enabling the rcpc extension does not change GCC code generation, and is just an assembler flag. But for completeness, here is documentation for the new option. gcc/ 2017-07-03 James Greenhalgh * doc/invoke.texi (rcpc architecture extension): Document it.
