Includes standard mathematical functions. Can compile for different instruction sets from the same source code. Can modify symbol names in object files. Can build, modify and convert function libraries across platforms.
Can dump object files and executable files. Source code included GPL. This is a library of elf bot 86 download 64 bit download subroutines coded in assembly language. Gnu general public license applies. This is a proposal and discussion of how an ideal instruction set architecture can be constructed. The proposed instruction set combines the best from the RISC and CISC principles to produce a flexible, consistent, modular, orthogonal, scalable and expansible instruction set for high performance microprocessors and large vector processors.
The ForwardCom instruction set has variable-length vector registers and a special addressing mode that allows the software to automatically adapt to different microprocessors with different maximum vector lengths and make efficient loops through arrays regardless of whether the array size is divisible by the vector length.
Standardization of the corresponding ecosystem of ABI standards, function libraries, compilers, etc. Test programs that I have used for my research. Can measure clock cycles and performance monitor counters such as cache misses, branch mispredictions, resource stalls etc. Can also set up performance monitor counters for reading inside another program. Supports Windows and Linux, 32 and 64 bit mode, multiple threads. Useful for analyzing small pieces of code but not for profiling a whole program.
