Description Ralf Corsepius 2004-05-23 01:20:47 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1)

Description of problem:
With GCC's CVS repository,
cvs co -rgcc_3_4_0_release 
cvs diff -uN -rgcc_3_4_0_release 
generates bogus diffs.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Check out a copy gcc-3.4.0 from GCC's CVS (cf. http://gcc.gnu.org)
cvs co -r gcc_3_4_0_release

2. Run
cvs diff -uNR -r gcc_3_4_0_release

Actual Results:  The resulting diff contains diffs against files that
try to remove files that are not present in gcc_3_4_0_release.

cvs diff -uN -r gcc_3_4_0_release gcc/config/sparc/t-linux
Index: gcc/config/sparc/t-linux
RCS file: gcc/config/sparc/t-linux
diff -N gcc/config/sparc/t-linux

-# Compile libgcc2.a with pic and IEEE quad long double.
-TARGET_LIBGCC2_CFLAGS = -fPIC -mlong-double-128

As it seems to me these are files had both been tagged
"gcc_3_4_0_release" and had been "cvs rm"'ed.

Expected Results:  The diff should be empty. 

Additional info:

I had tried to file this as a PR into GCC's bugzilla, but the GCC
maintainers blame "my cvs to be broken".
