Julian Seward	a0bf8f8271	Minor refinements: ... * h_main.c: handle a few more syscalls * exp-ptrcheck.supp: ignore errors in glibc's getenv -- is highly optimised * pc_common.c: fix small error in error message printing --> 3_4_BRANCH git-svn-id: svn://svn.valgrind.org/valgrind/trunk@9061	2009-01-26 00:09:08 +00:00
Nicholas Nethercote	5ad1dd61f9	Introduce a new type, PtrdiffT. Replace lots of uses of OffT (all those ... that are memory offsets) with PtrdiffT; OffT should only be used for file sizes and offsets. Change Off64T from a ULong to a Long, as it should be. Replace some uses of ULong in the address space manager with Off64T to match. Also add a comment explaining the meanings of the basic types like Addr, OffT, SizeT, etc. Also fix the prototype for VG_(pread) -- the last arg is an OffT, not an Int. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@8959	2009-01-15 21:29:24 +00:00
Julian Seward	25445f9819	On ppc32/64 we don't have a reliable way to detect function entries ... and exits at the moment. So disable stack array bounds checking for ppc32/64 platforms. Also (unnecessarily) disables global array bounds checking on those platforms. Add a flag --enable-sg-checks=no|yes [yes] so that stack and global checking can be optionally disabled on any platform. This is useful because stack and global checking is much more expensive than heap checking, and so it may be desirable to disable it. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@8686	2008-10-20 23:33:49 +00:00
