C Compiler M3T-NC308WA
Upgraded to V.5.20 Release 1
|
|---|
We have upgraded the M3T-NC308WA C-compiler (with an assembler and integrated development environment)
for the M32C/80 and M16C/80 series MCUs from V.5.10 Release 1 to V.5.20 Release 1.
- Descriptions of Upgrade
- 1.1 Functions Introduced
-
| (1) |
The High-performance Embedded Workshop supported. |
| (2) |
The following ten command options have been added:
| * | -fno_switch_table (-fNST)--Suppresses generation of code using a table jump for a switch statement |
| * | -fswitch_other_section (-fSOS)--Puts table code for a switch statement in a section other than the program section. |
| * | -fmake_vector_table (-fMVT)--Generates variable vector tables automatically. |
| * | -fmake_special_table (-fMST)--Generates special page tables automatically. |
| * | -Oforward_function_to_inline (-OFFTI)--Performs inline expansion for all the inline functions. |
| * | -Ofloat_to_inline (-OFTI)--Performs inline expansion of the run-time routine for executing floating-point operations to enhance the performance of these operations. |
| * | -Oglb_jmp (-OGJ)--Selects the most appropriate jump instruction at linking. |
| * | -Wno_used_function (-WNUF)--Outputs a warning message when a function not yet used in the application program is detected. |
| * | -Wstop_at_link (-WSAL)--Suppresses creation of absolute module files when a warning message is output at linking. |
| * | -Wundefined_macro (-WUM)--Outputs a warning message when a symbol not yet defined as a macro is used in a #if statement. |
