Bah. Latest run shows (as of r143125) failures still. 

gcc.apple/block-debug-1.c scan-assembler \\.Lstring12:[\\n\\r \\t]+\\.ascii\\s+"__block_descriptor"
gcc.apple/block-debug-1.c scan-assembler \\.Lstring12[^\\n\\r]+DW_AT_name
gcc.apple/block-debug-1.c scan-assembler \\.Lstring13:[\\n\\r \\t]+\\.ascii\\s+"__block_literal_generic"
gcc.apple/block-debug-1.c scan-assembler \\.Lstring13[^\\n\\r]+DW_AT_name

It does appear to have pulled the changes:
U    gcc-4_2-testsuite/src/gcc.dg/debug/dwarf2/var1.c
U    gcc-4_2-testsuite/src/gcc.apple/block-debug-1.c
U    gcc-4_2-testsuite/src/gcc.apple/block-debug-2.c
Updated to revision 143125.

Not quite sure what's going on. You may be spot on that your regex-fu is better than dejagnu's.
