See the Sourceforge download page for the last released version including source and binary packages for Linux - amd64, Microsoft Windows - x86, Microsoft Windows - amd64 and Mac OS X - ppc and amd64.

Major Linux distributions take care of SDCC installation packages themselves and you will find SDCC in their repositories. Unfortunately SDCC packages included in Linux disributions are often outdated. In this case users are encouraged to compile the latest official SDCC release or a recent snapshot build by themselves or download the pre-compiled binaries from Sourceforge download page.

Research compilers are mostly not robust or complete enough to handle real, large applications. They are used mostly for fast prototyping new language features and new optimizations in research areas.

While NoICE could have been made to load symbols and line numbers in other formats, this would have made the program larger, and would have restricted the number of formats supported. Instead, we decided to write small utility programs that process the output of various cross compilers, assemblers, and linkers. The output of this processing is a NoICE command file (.NOI file) containing DEF (define) commands for the symbols to be defined, and FILE and LINE commands for line number definitions. The command file may then be PLAYed by NoICE to define the symbols and line numbers. Thus, a new compiler or assembler may be supported simply by writing the appropriate utility.

The NoICE package includes symbol and line number processing utilities for a number of popular assemblers and compilers. The source code for most of these utilities is available to licensed NoICE customers, in case they wish to customize them, or write a similar utility for use with another assembler or compiler.

COFF (Common Object File Format) comes from the land of Unix. COFF files contain symbol and debug information for C and assembler programs. Unfortunately, there is not real standard for COFF: every compiler and assembler seems to produce a slightly different format. COFFNOI.C is intended as a starting place from which you can derive a COFF processor for your tools. The source code to COFFNOI.C is available to registered NoICE customers.

Dunfield Micro-C is low-cost C compiler. It does not support long, float, enum, typedef, or bit fields. However, it does support structs and modern style (as well as K&R) function prototypes and is therefore far more capable than Small-C. Pointer arithmetic is non-standard, but quite functional.

Versions 3.15 and later of Micro-C can generate symbolic information for use by NoICE by using the new "-S" compiler switch. The NoICE utility MAPNOI processes the listing file containing this information. It produces a NoICE command file that contains FILE and LINE commands for source level debug, and DEFINE commands to define global, static, and automatic symbols along with their datatypes.

The Open Source GNU GCC C compiler is available for a number of targets supported by NoICE,including HC11, HC12, MSP430, and ARM. All of these generate Elf files. GCC430 generatesdebug information as Stabs, while the other compilers generate debug information using Dwarf.By default, these files will have a .abs extension. To see these files in the Load File dialog, change "Files to type" to "Elf Files".

You must use the appropriate compiler switches to generate debug information. Usuallythis is "-g" for the compiler (gcc). The debug switch for the assembler (as) differs fromtarget to target. Consult your GNU documentation to see if you should use "-g", "--gdwarf2","--gstabs", or some other switch.

IAR sells C compilers and assemblers for most of the microprocessors supported by NoICE. The IAR linker can generate a wide variety of output formats. The formats available differby target architecture. The following list is in order of decreasing preference:

Please note that the free versions of the IAR compilers, including the MSP430 Quick Start, do not produce correct UBROF per the IAR documentation. The output of these compilers cannot be used with NoICE.

The NoICE utility IAR_NOI processes an UBROF file to extract symbol and line number information for source-level debugging with NoICE. IAR_NOI supports up to version 8 of UBROF. Later versions primarily add features for C++ that are not relavent for NoICE. If your compiler generates a later version of UBROF, you can adjust the settings to generate an earlier version.

Note: there seems to be a remarkable amount of difference in the UBROF produced by IAR compilers for different processors. Our testing has been performed with the compilers available to us. If you encounter problems, please contact us.

Version 6 and later of the compiler can generate debug files in the ImageCraft .DBG format. NoICE can LOAD the .DBG files to extract symbol and line number information for source-level debugging. This is required for source-level debugging. An .S19 or Intel hex file contains only program data. The .DBG file contains the debugging information.

Note: For compiler versions 3.6 and later, the linker switch "-g" generates a NoICE command file containing source line and global symbol information. However, this debug information does not include automatic (stack-relative) symbols or data type information. The file thus produced will have a ".CMD" extension, rather than the standard ".NOI" extension. If you PLAY this file, you must also LOAD the associated .S19 file. If you are using version 6 or later of the ICC compiler, we recommend that you LOAD the .dbg file rather than using the .cmd file.

A format called OMF51 is widely supported by compilers and assemblers for the 8051. The original standard was released by Intel and is available on the Web. Keil has extended OMF51 to add support for data types and additional information not supported by Intel OMF.

P&E sells BDM dongles and other hardware and software. To support their debuggers, they have defined a debug file format called P&E Map Files. A number of free and commercial assemblers and compilers can produce this format.

SDCC is a free open source compiler for the 8051, Z80, and HC08. Source code is available. Versions 2.1.8 and later can produce debug information files with a .CDB extension by means of the --debug switch.

There is one native z80 c compiler that I've found performs surprisingly well in benchmarks, and that's Hitech C v309 for CP/M. Unfortunately it's for CP/M as the name suggests, but it's worth a mention because it is steps above the others.

I'm afraid that with this: "Produces decently-optimized machine code" there will be no answer. Even contemporary cross-compilers (i.e. pc hosted) like sdcc or iar C produce miserably slow code for Z80 target.

A new release of SDCC, the portable optimizing C compiler for STM8, MCS-51, DS390, HC08, S08, Z80, Z180, Rabbit, SM83, eZ80 in Z80 mode, Z80N, TLCS-90, 6502, Padauk and PIC microprocessors is now available. Among many new features, the ubiquitous compiler has started to support 6502 output. The development is still ongoing but progresses fast.

CLion is an IDE that offers a lot of features to help developers. It shows documentation popups, detects mistakes on the fly, suggests fixes, and more. An internal code analyzer always works in the background, analyzing C and C++ code as you type. C and C++ are challenging languages for automatic analyzers because compiler-specific data is required to parse the code correctly. The engine needs to know the header search paths, predefined macro definitions, and some other details.

When CLion parses a project and encounters a compiler for a project file, CLion scans the sections one by one and checks whether the compiler matches the records. The matching is done using one or more matching records. The available matching records include:

The stub is:compilers: - description: SDCC for PIC-16 match-compiler-exe: "(.*/)?sdcc(.exe)?"For now, we only match by name. It is a regular expression matching both Linux and Windows compiler binary names regardless of the containing folder.

If the project is not loaded correctly, you should double-check the match-compiler-exe statement in the YAML file. The record value is a regular expression, and it is the most fragile part of the process. Please refer to these examples in case of problems.

Last but not least, we need to make our compiler matching a bit more specific by using match-args: -mpic16 and match-language: C statements, and then add SDCC language extension words as empty defines. Once we do, the final YAML file will look as follows:compilers: - description: SDCC for PIC-16 match-compiler-exe: "(.*/)?sdcc(.exe)?" match-args: -mpic16 match-language: C include-dirs: - $compiler-exe-dir/../include/pic16 - $compiler-exe-dir/../include - $compiler-exe-dir/../non-free/include/pic16 - $compiler-exe-dir/../non-free/include defines-text: "#define __SDCC_USE_NON_FREE 1#define __SDCC_PIC18F452 1#define __18f452 1#define __STACK_MODEL_SMALL 1#define __SDCC_pic16 1#define __SDCC_ALL_CALLEE_SAVES 1#define __STDC_VERSION__ 201112L#define __STDC_HOSTED__ 0#define __SDCCCALL 0#define __STDC_UTF_16__ 1#define __SDCC_VERSION_MINOR 2#define __STDC_ISO_10646__ 201409L#define __SDCC_VERSION_PATCH 0#define __SDCC_VERSION_MAJOR 4#define __STDC_NO_VLA__ 1#define __SDCC 4_2_0#define __STDC_UTF_32__ 1#define __STDC_NO_THREADS__ 1#define __SDCC_CHAR_UNSIGNED 1#define __STDC_NO_ATOMICS__ 1#define __STDC__ 1#define __SDCC_REVISION 13081#define __STDC_NO_COMPLEX__ 1#define __interrupt#define __code#define __at"Now we can reload the project (Tools Makefile Reload Makefile Project) and check the main.c file again. 2ff7e9595c
