Chris Lattner 1f4642c47c Handle passing constant integers to functions much more efficiently. Instead ... of generating this code: mov %EAX, 4 mov DWORD PTR [%ESP], %EAX mov %AX, 123 movsx %EAX, %AX mov DWORD PTR [%ESP + 4], %EAX call Y we now generate: mov DWORD PTR [%ESP], 4 mov DWORD PTR [%ESP + 4], 123 call Y Which hurts the eyes less. :) Considering that register pressure around call sites is already high (with all of the callee clobber registers n stuff), this may help a lot. llvm-svn: 12028		2004-03-01 02:42:43 +00:00
