x86/Pentium Cross Optimizing Compilers

The Green Hills Optimizing Compiler for x86/Pentium utilizes a common code generator with architecture-specific optimizations. Each supported x86/Pentium model has its own particular pipeline and instruction set characteristics. These are accommodated in the code generator to produce code best suited for the target processor. The following x86/Pentium-specific features are supported:

Processor—One option for each supported x86/Pentium model. This setting determines the
instructions permitted, as well as the pipeline optimization strategy used.

fprecise—Stores all floating point calculations in memory to ensure precise truncation. Fully compatible with the GNU convention for handling floating point comparisons, including comparisons that involve NANs.

ffunctions—Enables the compiler to use the 387 hardware instructions for certain floating point functions instead of calling them in the library.

Long Long Support—Fully supports 64-bit data types, constants, and expressions through the long long data type.

Start-up Code—Start-up code supports the romcopy layout.

Hardware Coprocessor—In hardware floating-point (HFP) mode, the compiler uses floating-point registers to hold floating-point data and to perform floatingpoint operations.

Floating-Point Built-ins—Controls the use of floatingpoint intrinsics, such as FABS, FSQRT, and FSIN.

Placement of Zero-Initialized Data—Controls the allocation of variables and arrays explicitly initialized to zero. Allocating such objects to an uninitialized section will generally reduce the size of the executable ROM image.
