helixhorned 792ac2fdf0 Optimization of C replacements of basic texture mapping functions, part 1 ... Affected functions: hlineasm4, vlineasm1, mvlineasm1, tvlineasm1. Optimizations: - declare all used variables as possibly const-qualified locals in each function. This removes unnecessary loads from memory in the loops. - rewrite "for (; cnt>=0; cnt--) {...}" to "cnt++; do {...} while (--cnt);" in the three last ones (yes, these function iterate cnt+1 times). This makes them functionally equivalent to the asm versions (madness ensues for cnt < 0) and allows the compiler to remove one 'test' instruction at the end of each loop. - in the translucence function, replace addition by ORing Observations (system: Core2 Duo Linux x86_64): With a 1680x1050 window fully covered by the respective type of wall (simple, masked, trans. masked), fps increases by 3-4 from the baseline of approx. 60. git-svn-id: https://svn.eduke32.com/eduke32@2405 1a8010ca-5511-0410-912e-c29ae57300e0		2012-03-04 20:12:30 +00:00
