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.

psd Add the source .psd files for the EDuke32 logo and program icon to the repository. Though they are .psd, they are effectively vector because they utilize paths. 2012-02-25 02:57:59 +00:00

Windows Remove four self-assignments in backtrace.c that were added to avoid an unused parameter warning and add ATTRIBUTE((unused)) to the implicated parameters so they will not trigger the warning because they could not be removed. 2012-03-04 09:31:02 +00:00
backtrace.dll Pull in backtrace.c (pre-compiled as backtrace.dll and MinGW dependencies) from http://code.google.com/p/backtrace-mingw. When running debugging snapshots, this will print out a helpful backtrace in eduke32.crashlog. I had to disable stack protectors for debug builds as this was pulling in a dependency that I assume most people won't have. If anyone feels like merging that code into EDuke32 itself and find a way to remove the ugly libintl dependencies, be my guest. In the meantime, sorry for the awful commit. 2010-10-19 05:42:21 +00:00
