V1.55q

Jun. 16

2005

Fixed: When using option “-ar”, the address calculation for switch statement is

incorrect.

Fixed: If the function located in EEPROM area is declared without pragma of “eep_seg”

like the following example, the redefinition error is generated.

Ex>

void eepFunc(void);

#pragma memory=eep_seg()

void eepFunc(void) // Redefinition error should not be generated.

{ }

#pragma memory=default

Ext: When accessing the element of multi-dimensioned array, the calculation of the

access address is executed by a 16-bit operation, so improving the code density and

performance.

Ext: The option “-bigoffset” is newly added. It makes 32-bit operation instead of 16-bit

operation when calculating access address of array’s element.

V1.55f

Mar. 2

2005

Ext: Remove setting the entry point as “_main” for the starting location of debugging.

Instead of compiler, linker will do it.

V1.55d

Feb. 18

2005

Fixed: R0 reg. is not pushed/poped in optimization level 0 in using it.

Ex>

void foo(void)

{

// When initializing local array, R0 reg. is used. So R0 reg. should be

// pushed and popped in function prolog and epilog.

char c[2] = {0x11, 0x22};

}

V1.55c

Jan. 26

2005

Fixed: Cast not applied when a pointer variable is casted “void*” to “generic int*”.

Ex>

generic char* myptr;

void foo(void)

{

// Because “myptr” casted to final type “generic int*”, the library

// call that dereferences a generic pointer should be generated.

int x = *(generic int*)(void*)myptr;

}

V1.55a

Dec. 20

2005

Fixed: Executed as a 16-bit operation when shift 4 bytes variable in both(left, right)

directions.

Ex>

unsigned char* ptr;

struct APPLE {

unsigned int weight;

} *ptr2;

void foo(void)

{

// the shift left should be executed as a 32-bit operation

ptr = ptr - ((unsigned long)ptr2->weight << 2);

}
