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.
Iar C Compiler Z80 17
Download: https://urlcod.com/2vEDiI
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.
I am using code compiler for my development purpose . When I try to access the bit property of this contrroller , I always get an error . One of the program I am attaching here for your reference . This program I have taken from some sample code , in the code they have asked to use header file as "" but I am not able to find that file in the directry. Some article says is for IAR . However I tried with both the compiler and gets the same error . The error is pasted below the code .Please help me to resolve this

MSP430 have bit,bis.and bic (unlike some other mcu) that also comes in 8bit .b version that the IAR compiler will use properly and many msp registers are 8bit only.The complier will notice if a few bit changes in a row have the same destination register and will merge them in to one instruction.So set optimization to med or high and look at the tight code IAR makes.
Second operation is of no difference but if you give the compiler high optimization level and this can group bit field operation together the behaviour of bit pattern change in time, no more bit instruction time is between bit set/reset but all chenge at same time.
if you use a var through a bitfield the compiler knows to treat it as a 0 or 1 boolen. P1OUT_bit.P2 = P1IN_bit.P3 is perfectly OK (P1OUT & BIT2) = (P1IN & BIT3) would NOT work. You could fix that with: (P1IN & BIT3) ? (P1OUT BIT2) : ( P1OUT & BIT2) The bitfield version above using optimization ends up doing that in the resulting machine-code. If the compiler bunch together bit banging bits but you're doing your own data/clk system, there is #pragma optimize=3 z On ARM with its use of bit-banding to access bits in a single atomically instruction, would it help the compiler to do that all the time if it's a bitfield variable? Is bitfeild and io430.h getting deprecated (phased-out) or is it being more acceptable?As io430 still can be used as the same was as you would with mp430.h, and don't see why not make it the default(?)

Sorry I don't know so in deep ARM, I was proud in old 1987 to demonstrate ARM was inferior to 68000 code but not now I am using ARM from C as is. My preferred RISC architectures was 88000 able to responf to interrupt in just one clock cycle. Time elapsed ant that ultrafast power horse got rest house as for PARISC powerPC as RS/6000 too.
The compiler saw func before saw its declaration, so compiler will generate an implicit declaration: int func();, its return type is int by default. That's not what you meant. To correct it, use this:
The C compiler is a one-pass compiler. It starts at the beginning and when it gets to the end, it's done. When it sees you using the function before you've told the compiler that it exists, then you get this error/warning.
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.
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
