annotate dmd/mtype.c @ 217:0806379a5eca trunk
[svn r233] Added: -oq command line option for writing fully qualified object names.
Added: started support for x86 80bit floating point.
Changed: aggregates passed by value now use the llvm 'byval' parameter attribute, also lays ground work for
using other attributes.
Changed: eliminated a lot more std::vectorS, these showed up pretty much at the top when profiling!
Changed: performed other misc. cleanups.
Changed: halt expression now call the new llvm trap intrinsic instead of an assert(0).
Changed: dstress suite now passes -O0 by default, this only eliminates unreferenced globals, which speeds up
linking quite a bit.
