on 32 bits memcheck default nr of sectors). Memory is reduced by using UShort typedef-s for Sector no and TTE no. Note that for TTE no, we had a mixture of UShort, UInt and Int used depending on the place (a TTE no was in any case constrained to be an UShort). The bss memory/startup space is also reduced by allocating the htt on demand (like tt and tc), using mmap the first time a sector is initialised. Changes: * pub_core_transtab.h : * 2 typedef to identify a sector and a tt entry (these 2 types are UShort) * add 2 #define 'invalid values' for these types * change the interface to use these types rather than UInt * m_transtab.c * use wherever relevant these 2 new types rather than UInt or UShort * replace the use of -1 by INV_SNO or INV_TTE * remove now useless typecast from Int/UInt to UShort for tte * schedule.c: use the new types git-svn-id: svn://svn.valgrind.org/valgrind/trunk@15036
