next in thread | raw e-mail | index | archive | help
in a related tangential note, i recently found (out of sheer irritation)
in less than an hour that several (including the latest) versions of GCC
 -O and -O2 failed the paranoia test in different ways, to wit:

gcc -o paranoia paranoia.c

[paranoia output elided]

The number of  DEFECTs  discovered =         1.
The number of  FLAWs  discovered =           1.

gcc -O2 -o paranoia paranoia.c

[paranoia output elided]

The number of  FAILUREs  encountered =       4.
The number of  SERIOUS DEFECTs  discovered = 4.
The number of  DEFECTs  discovered =         2.
The number of  FLAWs  discovered =           2.

i assume everyone knows about kahan and paranoia. if not see netlib.
