PRODUCT OVERVIEW
ANSI Standard X3.1591989 Passes Plum Hall Conformance Perennial Tests
Supports In-Line
Intel's CTOOLS provides complete application development tools developing embedded designs, including advanced optimizing compilers, assembler, linker, utilities, based debugger, variety libraries, including floating-point emulation. Besides operating with most popular operating systems, CTOOLS also incorporates industry standards areas. compiler conforms ANSI Standard X3.159-1989 passes Plum Hall conformance Perennial test suites. CTOOLS also conforms 80960 Application Binary Interface (ABI), enabling object code interoperability with third-party tools debuggers. Compatibility with known standards makes users productive immediately, ensures access existing application code. CTOOLS used across members i960® microprocessor family. Command line switches allow compiler take advantage specific architectural features. instance, case i960 processors, compiler uses advanced code scheduling algorithms modify instruction sequences, taking advantage processor's parallel execution capability. generated code highly efficient, assuring maximum performance your embedded applications.
PROVEN OPTIMIZATION TECHNIQUES
Assembly Code C/C++ Source
Includes IEEE-754
Compatible, High-Speed, Accelerated FloatingPoint Library Components Without On-Chip Floating-Point Instructions
Supports Windows
Windows Selected UNIX Hosts
Source Code Supplied
Advanced optimization techniques incorporated into Intel's CTOOLS compiler offer customers superior performance while maintaining robust code. compiler incorporates local, global, program-wide profiledriven optimizations.
PROCESSOR INDEPENDENT OPTIMIZATIONS INCLUDING:
Constant expression evaluation Constant propagation Collapsing arithmetic bitwise boolean
Procedure inlining Branch optimizations Dead code elimination Loop invariant code motion Variable shadowing Superblock formation Basic block rearrangement
identities
Common subexpression elimination Register subsumption register coalescing Local variable promotions Tail-call elimination
PROCESSOR DEPENDENT
Specialized instruction selection intelligent register manager Code scheduling on-chip data frequently used
Efficient complex addressing modes Branch prediction Generation leaf procedures Memory access coalescing
variables
WHOLE-PROGRAM PROFILE-DRIVEN OPTIMIZATIONS
CTOOLS also provides program-level optimizations, which allow optimizations such function inlining occur across source files. Changing optimization level simple changing argument compiler's command line. Restructuring your build environment longer needed! runtime profile used guide whole-program optimization decisions. Such profile-driven optimizations combine global view entire program with typical runtime behavior, produce highly optimized code. Collecting runtime profile often expensive procedure. With CTOOLS, once runtime profile collected, used guide optimizations after days, weeks even months changes your source code. profile automatically interpolated match structure your program.
COMPRESSION ASSISTED VIRTUAL EXECUTION (CAVE)
storing non-critical functions compressed form, CTOOLS save valuable memory your ROM-based application. When invoked, such functions decompressed onto runtime stack executed. Upon function return, stack space automatically freed.
DEBUGGING OPTIMIZED CODE
DWARF symbolic debug information format supports expression complex relationships between your source program highly optimized object code. Debugging features such breakpoints displaying variable's value behave more reliably with DWARF than with existing object file formats such COFF b.out, when your code optimized. Optimized code debugging often eliminate expensive step building unoptimized version your application debugging purposes.
ASSEMBLER LINKER
assembler processes assembly code produced compiler. CTOOLS toolset offers other valuable utilities such Debugging aids: object file dumper COFF IEEE-695 object file converter mapper big-endian little-endian object file converter archiver build libraries object file stripper eliminate debug builder produce ROMable code records from object module
linker links together separately compiled modules, performing additional optimizations such replacing calls branch-and-link sequences. reads contents configuration file order application's code data sections memory then link correct run-time libraries application. Linkage performed interactive steps until final link step, which time unresolved externals satisfied.
DEBUGGER MONITOR
gdb960 symbolic debugger MON960 monitor included CTOOLS. debugger full symbolic debugger, operates with MON960 monitor allow setting breakpoints, single-stepping, variable tracing, many other capabilities. debugger easy Graphical User Interface (GUI).
LIBRARY SUPPORT
CTOOLS supports three library types:
i960 architecture-specific high-level C/C++ libraries IEEE-754 compatible accelerated floating-point libraries Low-level libraries supporting i960 processor evaluation boards
CTOOLS linker configuration files hide complexity linking correct libraries. C/C++ libraries have been optimized generated using CTOOLS compiler. They offered normal code form, position-independent form applications relocatable load time, big-endian form applications that i960 processor big-endian memory regions.
TECHNICAL SUPPORT
