The Secure Coding Initiative at CERT has published a new Technical Note
CMU/SEI-2009-TN-023 entitled "As-if Infinitely Ranged Integer Model".
Abstract:
Integer overflow and wraparound are major causes of software vulnerabilities in
the C and C++ programming languages. In this paper we present
Hello!
The source of gcc uses both, fputc and putc. I would like to do some
janitorial work and change fputc to putc.
The reason is, that in system.h, both of them get redefined to the
corresponding unlock function:
# ifdef HAVE_PUTC_UNLOCKED
# undef putc
# define putc(C, Stream) putc_unlocked

Hi,
I have a question about modelling of condition codes in GCC. The
target I am considering has the following characteristics:
Associated with each register is a set of CC flags that are updated
whenever that register is used as a destination of an operation that

Hello,
This patch adds dummy implementation for

This model still seems extremely poorly defined. The only sensible way to
fix this is a careful definition of the AIR abstract

As further comments, it's unfortunate that this document has chosen
certain badly thought out basis documents and concepts.
On page 13 you have a short table of "critical undefined behavior" and an
attempt to define "bounded undefined behavior", that ignore all my
previous comments in this area

putc and fputc have different semantics:
fputc is guaranteed to be a function while putc may be a macro.

This merge brings in unit-at-a-time gimplification, so it needed some
tweaking. Mostly, it helped to find out some GENERIC that was leaking
into the streamer. A pleasant side-effect of the unit-at-a-time
gimplification is that not every function is gimplified, so there is
less gunk to pickle out

even though VTA is not completely finished, it's already enough of an
