This patch adds an expected checksum for the tests expecting an asm diff. This way if we were expecting an asm diff, still get one, but a different one, we know (before this patch we would ignore this, generating an XFAIL as usual, as the status of "having an asm diff" itself hadn't changed). I had to change from using the TCL grep to the bash grep (through an exec call) as I now need the actual output of the grep call, not only the return value (it also turns out the return value for TCL grep and bash grep are different; hence the change in the if statements on the adiff variable) Gab 2011-07-15 Gabriel Charette <gchare@google.com> * g++.dg/pph/c1builtin-integral.cc: Add expected diff checksum. * g++.dg/pph/c1eabi1.cc: Add expected diff checksum. * g++.dg/pph/p4eabi1.cc: Add expected diff checksum. * lib/dg-pph.exp (dg-pph-pos): Expect checksums for pph asm xdiff. diff --git a/gcc/testsuite/g++.dg/pph/c1builtin-integral.cc b/gcc/testsuite/g++.dg/pph/c1builtin-integral.cc index c2fceec..6887b11 100644 --- a/gcc/testsuite/g++.dg/pph/c1builtin-integral.cc +++ b/gcc/testsuite/g++.dg/pph/c1builtin-integral.cc @@ -1,2 +1,2 @@ -// pph asm xdiff +// pph asm xdiff 52758 #include "c0builtin-integral.h" diff --git a/gcc/testsuite/g++.dg/pph/c1eabi1.cc b/gcc/testsuite/g++.dg/pph/c1eabi1.cc index b127f98..3321870 100644 --- a/gcc/testsuite/g++.dg/pph/c1eabi1.cc +++ b/gcc/testsuite/g++.dg/pph/c1eabi1.cc @@ -1,5 +1,5 @@ // { dg-options "-w -fpermissive" } -// pph asm xdiff +// pph asm xdiff 36206 #include "c0eabi1.h" diff --git a/gcc/testsuite/g++.dg/pph/p4eabi1.cc b/gcc/testsuite/g++.dg/pph/p4eabi1.cc index 4247f49..2f0715f 100644 --- a/gcc/testsuite/g++.dg/pph/p4eabi1.cc +++ b/gcc/testsuite/g++.dg/pph/p4eabi1.cc @@ -1,5 +1,5 @@ // { dg-options "-w -fpermissive" } -// pph asm xdiff +// pph asm xdiff 15662 #include "p4eabi1.h" diff --git a/gcc/testsuite/lib/dg-pph.exp b/gcc/testsuite/lib/dg-pph.exp index b706f27..1d7deed 100644 --- a/gcc/testsuite/lib/dg-pph.exp +++ b/gcc/testsuite/lib/dg-pph.exp @@ -128,12 +128,11 @@ proc dg-pph-pos { subdir test options mapflag suffix } { verbose -log "" # Compare the two assembly files.

Reviewed in person by Lawrence. Shortened XFAIL message from previous patch. Also, quick side note, in the first description of this patch I said I used "exec grep", I meant "exec diff".

OK with the change below. Diego. http://codereview.appspot.com/4744043/diff/3001/gcc/testsuite/lib/dg-pph.exp File gcc/testsuite/lib/dg-pph.exp (right): http://codereview.appspot.com/4744043/diff/3001/gcc/testsuite/lib/dg-pph.exp#... gcc/testsuite/lib/dg-pph.exp:131: set adiff [catch {exec diff "$bname.s-pph" "$bname.s+pph"} diff_result] 131 set adiff [catch {exec diff "$bname.s-pph" "$bname.s+pph"} diff_result] You don't need this, if instead of summing the diff you sum $bname.s+pph. The logic would then be: if there is a difference between $bname.s-pph and $bname.s+pph, we checksum $bname.s+pph. If the new checksum is different than the stored one, it means that $bname.s+pph is different from $bname.s-pph in a different way. This has the benefit of: - Being slightly faster. - Simplifies the generation of checksums. We no longer need to checksum the difference between the two .s files, we just need to checksum the .s+pph file

See below. http://codereview.appspot.com/4744043/diff/3001/gcc/testsuite/lib/dg-pph.exp File gcc/testsuite/lib/dg-pph.exp (right): http://codereview.appspot.com/4744043/diff/3001/gcc/testsuite/lib/dg-pph.exp#... gcc/testsuite/lib/dg-pph.exp:131: set adiff [catch {exec diff "$bname.s-pph" "$bname.s+pph"} diff_result] I actually prefer checksum on the diff itself: It's less affected by merges (in particular the merge timestamp doesn't show up in the diff, so unless a merge from trunk changes the actual assembly, the diff is the same as before) Also, the generation of checksums is not harder this way, I made it so the tests' output tells you what the expected/actual sums are when they differ, so no need to generate them by hand.

OK, in that case go ahead. Diego.
