Armcc - The ARM C Compiler The ARM C Compiler armcc SYNOPSIS armcc [ options] sourcefile. DESCRIPTION The ARM C compiler is a mature, industrial-strength com- piler, based on Codemist Ltd's multi-target, multi- language compiler suite (also known as the Norcroft C com- piler). By default the ARM C compiler compiles ANSI C as defined by American National Standard for Information Systems - Programming Language C, X3J11/90-013, Feb 14, 1990. The ARM C compiler also has a pcc mode, which accepts the dialect of C used by Berkeley Unix.

In this mode the com- piler has been used to build a complete ARM-based Unix system (the RISCiX system). For more background about the ARM C Compiler, and for rec- ommended reading for C programmers, as well as full tech- nical information on the ARM C Compiler see 'The ARM C Compiler' of the Reference Manual. OPTIONS By default, the C compiler looks for source files, and creates object, assembler and listing files, in the cur- rent directory. Shotgun messiah second coming rar file. Many aspects of the compiler's operation can be controlled via command-line options. All options are prefixed by a minus sign.

The ARM Compiler is specifically designed to optimize software running on ARM processors. It is the result of 20 years of development alongside the ARM Architecture. The ARM Compiler toolchain incorporates a highly optimizing C/C++ compiler, assembler, linker and libraries for embedded software development. Arm Compiler 6 Downloads. Arm Compiler 6 can be used as a standalone tool (command line) or integrated into Arm DS-5 Development Studio ( installation instructions) or Keil MDK tool ( installation instructions) suites, depending on your license.

There are two classes of option: keywords and flags. Key- words are recognised in upper case or lower case. A flag is a single letter, the case of which is sometimes impor- tant to the ARM C compiler. Because some systems (such as Unix) are very case sensitive, the case of flags is most important when you are building portable makefiles.

By using the conventions common to many C compilers, you can move a makefile between different environments at minimum cost. Keyword Options -help Give a summary of the compiler's command line options. Ediabas

-pcc Compile (BSD 4.2) portable C compiler C. This dialect is based on the original Kernighan and Ritchie (K&R) definition of C, and is the one used on Unix systems. The -pcc keyword alters the lan- guage accepted by the compiler, but the built-in ANSI headers are still used. For more details on this, see section ' PCC Compatibility Mode' of the Be extra strict about enforcing conformance to the ANSI standard or to pcc conventions (e.g. Prohibit the volatile qualifier in -pcc mode). -list Create a listing file. This consists of lines of source interleaved with error and warning messages.

Finer control over the contents of this file may be obtained using the -f flag (see' Controlling Addi- tional Compiler Features' starting on page13). -littleend or -li Compile code for an ARM operating with little- endian (least significant byte has lowest address) memory.

-bigend or -bi Compile code for an ARM operating with big-endian (most significant byte has lowest address) memory. By default, the ARM C compiler compiles code with the same byte order as the host system. However, most releases of the ARM C compiler, for most hosts, allow this default to be configured when the compiler is installed, so it is not usually neces- sary to use either of these options (see ' The ARM Tool Reconfiguration Utility (reconfig)' for more information).

-apcs [3] qualifiers Specify which variant of the ARM Procedure Call Standard is to be used by the compiler. The default is set up when armcc is configured, and for ease of use can be reconfigured using the reconfig tool - see ' The ARM Tool Reconfiguration Utility (reconfig)' for details. Alternatively the default can be changed by use of this keyword option.

At least one qualifier must be present, and there must be no space between qualifiers. The following qualifiers are permitted: /26[bit] 26 bit APCS variant. /32[bit] 32 bit APCS variant. /reent[rant] Reentrant APCS variant. /nonreent[rant] Non reentrant APCS variant. Software stack checking APCS variant. /noswst[ackcheck] No software stack checking APCS vari- ant.

Registers For details of the various APCS variants see ' ARM Procedure Call Standard' starting on page 38 of the Technical Specifications. Flag Options The flag options are listed below. Some of these are fol- lowed by an argument. Whenever this is the case, the ARM C compiler allows white space to be inserted between the flag letter and the argument.
