RENESAS TOOL NEWS on April 1, 2004: RSO-M3T-NC8C-040401D

R8C/Tiny-only Free-version Compiler
M3T-NC8C
Upgraded to V.5.30 Release 1

We have upgraded the R8C/Tiny-only Free-version Compiler M3T-NC8C from M3T-NC30WA V.5.20 Release 1 to V.5.30 Release 1.

NOTE:
The product name of R8C/Tiny-only Free-version Compiler has been changed from M3T-NC30WA to M3T-NC8C on and after April 1, 2004.
R8C/Tiny-only free-version compiler M3T-NC8C was integrated into the evaluation version of C compiler package M3T-NC30WA for M16C series.

  1. Descriptions of Upgrade
    1.1  Functions Introduced
    (1) The following eight command options have been added:
    * -fno_switch_table (-fNST)--Suppresses generation of code using a table jump for a switch statement
    * -fmake_vector_table (-fMVT)--Generates variable vector tables automatically.
    * -Oforward_function_to_inline (-OFFTI)--Performs inline expansion for all the inline functions.
    * -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.
    * -Oglb_jmp (-OGJ)--Selects the most appropriate jump instruction according to the jump distance at linking
    (2) Option /E, which enables multiple interrupts, has been added to expanded function #pragma INTHANDLER (#pragma HANDLER).
