Thumbs up
It's the easiest way of parallel programming I've ever seen. In my opinion it's the origin of programmers (r)evolution :D...

xmtcc 0.81.3-alpha file released: xmtcc-0.81.3.src.tar.gz
version 0.81.3(r7965) + Fixed redirection problem to have success or failure printed when using the quiet flag (-q) (r7965) + Fixed issue with revision number not being updated (r7961) + Removed FPGA codesize check since new FPGA has I-Cache (r7961) + Removed deprecated puts and putchar functions from the linker (r7961) + Fixed floating-point compare and branch code generation (r7760) + Added support for fp instructions on the FPGA (r7620) + Updated Assembler Converter to allow assembling fp instructions (fp register arguments) (r7610) + Fixed compilation issue on newer linux distributions. (r7896) version 0.81.2 (r7965) + Added option -pref-bufs to specify the number of prefetch buffers on the target platform (r6266) + Fixed bug that made the check-pass crash on some machines because of failed pattern matching on the error message. (r5880) version 0.81.1 (r5839) + Added check pass to xmtcc script to give better error messages version 0.81.0 (r5781) + Made support for .xbo binary format the norm. + Updated documentation and removed old binary format options (only from the documentation) + Fixed an error in licensing (recovered removed FSF Copyright notices) + Fixed bug that deleted intermediate files even when partial compilation (i.e., -E, -C, -S, -c) was performed + Fixed an unmanifested bug where spawnLO was only broadcasted for the first thread executed per TCU. version 0.8.2 + Added -lg flag by default to allow loading of .32b files in the simulator version 0.8.0 + First Public Release Version + Major changes in GCC and CIL components used + GCC: + Changed the C language file to accept XMTC (added spawn and psBaseReg) + Changed scrips and Makefiles to avoid building unused libraries + Added xmt backend + CIL: + Added XMTC extensions to the supported C language + Changed internals to avoid flattening of scopes. The spawn semantics didn't allow for this.
