- Descriptions of Upgrade
- 1.1 New Features

- * Arguments of type float can be passed using registers
- 1.2 Problems Fixed
- (1) When a structure is defined which contains both bit field members and members of other types, compilation may not properly be performed.
- For details refer to MESC TOOL NEWS "CC32R Precaution" issued on March 16, 2000.
- (2) When two variables are the same in size and different in sign attribute and the result of assigning a variable to another one is used for operations between 4-byte variables of type int, these operations may not be performed correctly.
- For details refer to MESC TOOL NEWS "CC32R Precaution" issued on June 1, 2000.
- (3) When a function is called which returns a structure not an integer multiple of 4 bytes in size, and the return value is not referenced by any expression, the value of the stack pointer after the function call becomes incorrect.
- For details refer to MESC TOOL NEWS "CC32R Precaution" issued on June 16, 2000.
- (4) Defining structures containing bit fields of type char and the expressions for initializing them results in incorrect compilation.
- For details refer to MESC TOOL NEWS "CC32R Precaution" issued on September 16, 2000.
- (5) When a global variable is read three or more times successively in a C-language program, a code that reads out the variable may be generated in incorrect timing.
