RENESAS TOOL NEWS on November 16, 2003: RSO-M3T-CC32R_1-031116D
Cross-Tool Kit M3T-CC32R
Upgraded to V.4.20 Release 1
|
|---|
We have upgraded the M3T-CC32R Cross-Tool Kit for the M32R family MCUs from V.4.10 Release 1 to V.4.20 Release 1.
- Descriptions of Upgrade
- 1.1 Functions Introduced and Specifications Improved
-
| (1) | Single-precision mathematical function library introduced
Introduced a single-precision mathematical function library (header file mathf.h) for processing mathematical functions in single precision. This library gives you better performances in program execution than the C-language standard library (header file math.h). At the same time, a function that can handle FPU instructions of the M32R-FPU-cored M3218x group has been provided. When used together with the single-precision mathematical function library, it makes the processing of mathematical functions much faster. |
| (2) | High-performance Embedded Workshop bundled (PC version only)
The High-performance Embedded Workshop (an integrated development environment) that runs on the M3T-CC32R has been bundled, which allows you to create and manage projects and make builds.
The TM, another integrated development environment, is also bundled as before. |
| (3) | Debug information available full-time and the strip32R command added
In the cc32R C compiler, as32R assembler, and lnk23R linker, debug information has become available full-time, which allows you to dispense with the -g option.
On the other hand, the size of object and load module files grows larger since debug information resides in them all the time. In order to remove debug information from these files, the strip32R command has been supplied. Use this command if necessary. |
| (4) | Option -CS enhanced
Selecting the -CS option only can create an assembly source file containing C-source lines at compilation. Because this eliminates the need for the C source merge utility "cmerge", we discontinue including it in the product package. |
| (5) | Static variables placed in memory in order of declarations
Static variables, which have ever been placed in indefinite order, can be placed in memory in order of declarations. |
| (6) | Increased number of items in map files
The name of the source file and those of the debug symbols (the function name and the names of global variables of type int and pointer only) have been added to the output items of map files created by the map32R map generator. |
| (7) | Error handlings altered in the lnk32R linker
| * | When a section is incorrectly specified, the linker does not take it as an error but displays a warning message without discontinuing linking. |
| * | Detailed error information is displayed when relocation size overflows. |
| * | Only the first 20 errors and warning messages are displayed (this number is alterable). |
