RENESAS TOOL NEWS on December 26, 2005: RSO-M3T-NC308WA-051226D
The C Compiler Package M3T-NC308WA
Revised to V.5.40 Release 00 |
We have revised the C compiler package M3T-NC308WA from V.5.20 Release 02 to V.5.40 Release 00. This compiler package is used for the M32C/90, M32C/80, and M16C/80 series of MCUs.
- Descriptions of Revision
| 1.1 |
|
Functions Introduced and Improved
| (1) |
|
The M32C/90 series of MCUs newly supported by this version and later.
|
| (2) |
|
Code-optimizing capabilities enhanced. Examples of optimization are as follows:
- The controlling expression not generated of the "for" construct that executes its iteration statement only once.
- In the case where any statement or expression is repeatedly used in a program, it is made into a subroutine, to which calls are made instead of the statement or expression.
|
| (3) |
|
Optimizing options -OR_MAX and -OS_MAX introduced in the compiler.
Their functions are as follows:
-OR_MAX
Performs optimization that gives high priority to coding efficiency (equivalent to using all of these options, -O5, -OR, -OGJ, -OSA, -fCE, -fD32, -fNA, -fSA, -fUD, and -fNC).
-OS_MAX
Performs optimization that gives high priority to the speed of execution of user programs (equivalent to using all of these options, -O4, -OS, -OGJ, -OSA, -OSTI, -OLU=10, -fCE, -fD32, -fSA, -fUD, and -fNC).
|
| (4) |
|
The start-up program in the C language introduced in addition to the assembly language.
|
| (5) |
|
The en-size blank space usable for names of directories (folders) under which tool products are installed; and of the files and paths that the compiler, assembler, linker and others handle.
|
| (6) |
|
The type of the type definition size_t changed from unsigned int to unsigned long, and that of ptrdiff_t from signed int to signed long.
In addition, compile options -fsizet_16 and -fptrdifft_16 introduced to maintain compatibility with the previous versions. Option -fsizet_16 treats the type of size_t as unsigned int and -fptrdifft_16 does that of ptrdiff_t as signed int. |

The High-performance Embedded Workshop Revised
The High-performance Embedded Workshop that is bundled with the NC308WA has been revised from V.4.00.00 to V.4.00.03.
For detailed information on the revision, see the following items of RENESAS TOOL NEWS:
|
| 1.3 |
|
The AutoUpdate, an extended function of the High-performance Embedded Workshop V.4, has been revised from V.1.00.01 to V.1.00.02.
For details, see RENESAS TOOL NEWS RSO-AutoUpdate-051226D.
|
| 1.4 |
|
The "Simulator Debugger for M32C MCUs" which runs on the High-performance Embedded Workshop V.4.00.03 have been added
| 1.4.1 |
|
Functionality
The simulator debugger is provided with the functionality covering the following product:
Simulator Debugger M3T-PD308SIM
(for the M32C/90, M32C/80, and M16C/80 series of MCUs)
Main features in comparison with the above simulator debugger is as follows:
When the High-performance Embedded Workshop is used conventionally to develop programs for M32C MCUs, it performs builds of programs only, and any of the debuggers has to be used as an external development tool.
Now, running this simulator debugger on the High-performance Embedded Workshop V.4.00.03 enables you to debug programs using a simulator; that is, the emulators for the M32C MCUs can perform seamless operations of coding, compiling, simulating, and debugging under the single development environment of the V.4.00.03. So you need not invoke an editor, a compiler, a simulator debugger, and an emulator debugger independently.

| 1.4.2 |
|
Host System Requirements
Computer: IBM PC/AT compatible
OS: Windows XP, Windows 2000, Windows Me. or Windows 98SE
|
| 1.4.3 |
|
Main Points of Difference between this Simulator Debugger and the M3T-PD308SIM Simulator Debugger
| (1) |
|
If you run application programs created using the PDSDK COM kit on this simulator debugger, consult our technical support contact. |
| (2) |
|
This simulator debugger does not run in combination with ZIPC CASE tool, manufactured by CATS Co., Ltd. If you want to utilize ZIPC's debugging functions, use the M3T-PD308SIM simulator debugger. |
| (3) |
|
On this simulator debugger, the commands and windows created by the CB (Custom Builder) do not operate. |

For details, see RENESAS TOOL NEWS. |
| (5) |
|
On defining more than one void function
For details, see RENESAS TOOL NEWS. |
| (6) |
|

| (12) |
|
On changing the version or release of a tool chain to another(We informed you of this problem as the one arising from the High-performance Embedded Workshop in May 2005. However it has been found that the problem is caused by the M3T-NC308WA and M3T-NC30WA.)
