From c4fe3ea7cf2e9f261006ab7ea65bd20c60fe270c Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 17 Sep 2014 22:20:45 +0000 Subject: soft-fp: Fix comment formatting. This patch fixes formatting of comments in soft-fp (in particular, the normal style in glibc does not have a leading '*' on each line, and comments should start with capital letters and end with ". */"). Tested for powerpc-nofpu that the disassembly of installed shared libraries is unchanged by this patch. * soft-fp/extended.h: Fix comment formatting. * soft-fp/op-1.h: Likewise. * soft-fp/op-2.h: Likewise. * soft-fp/op-4.h: Likewise. * soft-fp/op-8.h: Likewise. * soft-fp/op-common.h: Likewise. * soft-fp/soft-fp.h: Likewise. --- soft-fp/op-common.h | 86 ++++++++++++++++++++--------------------------------- 1 file changed, 33 insertions(+), 53 deletions(-) (limited to 'soft-fp/op-common.h') diff --git a/soft-fp/op-common.h b/soft-fp/op-common.h index 5852a86a1b..ec0bc426e3 100644 --- a/soft-fp/op-common.h +++ b/soft-fp/op-common.h @@ -45,10 +45,8 @@ ?
