The patch does fix a number of the reverse regression test failures. 
However, the specific test that I am looking at, finish-reverse.exp, is
not fixed.  Here is the list of failures with and without your fix:


err file name 					no patch     louise patch
gdb.reverse/finish-reverse-bkpt.exp    		2      		2
gdb.reverse/finish-reverse.exp 			11      	11
gdb.reverse/fstatat-reverse.exp        		1       	1
gdb.reverse/next-reverse-bkpt-over-sr.exp      	2       	2
gdb.reverse/solib-precsave.exp 			17      	0
gdb.reverse/solib-reverse.exp  			17      	0
gdb.reverse/step-precsave.exp  			7       	0
gdb.reverse/step-reverse.exp   			7       	0
gdb.reverse/until-precsave.exp 			2      		2
gdb.reverse/until-reverse.exp  			1      		1

I will look a bit more into what your patch is doing and see if I can
understand what is going on in the finish-reverse.exp test with regards
to your patch.  Thanks for the help.
