What is SDCC?

SDCC is a retargettable, optimizing ANSI - C compiler that targets the Intel 8051, Maxim 80DS390, Zilog Z80 and the Motorola 68HC08 based MCUs. Work is in progress on supporting the Microchip PIC16 and PIC18 series. SDCC is Free Open Source Software, distributed under GNU General Public License (GPL).

Some of the features include:

•SDCC ASXXXX and ASLINK, a retargettable assembler and linker, is Free Open Source Software, distributed under GNU General Public License (GPL).
•extensive MCU specific language extensions, allowing effective use of the underlying hardware.
•a host of standard optimizations such as global sub expression elimination, loop optimizations (loop invariant, strength reduction of induction variables and loop reversing ), constant folding and propagation, copy propagation, dead code elimination and jump tables for 'switch' statements.
•MCU specific optimizations, including a global register allocator.
•adaptable MCU specific backend that should be well suited for other 8 bit MCUs
•independent rule based peep hole optimizer.
•a full range of data types: char (8 bits, 1 byte), short (16 bits, 2 bytes), int (16 bits, 2 bytes), long (32 bit, 4 bytes) and float (4 byte IEEE).
•the ability to add inline assembler code anywhere in a function.
•the ability to report on the complexity of a function to help decide what should be re-written in assembler.
•a good selection of automated regression tests.

tamamlanmasını merakla bekliyorum

tamamlanmasını merakla bekliyorum  

Tamamlanmasini bekleyeceksen, daha çok beklersin. 10 yillik proje.
Forumda kullanimini anlatacak makale bile yayinlanacakti neredeyse:

"In development" dedigi optimizasyonlar vs..
Microchipin C18 derleyecisinin Student versiyonunda daha iyidir yine de.
