[参考译文] MSP430FR2633：关于 CodeGen-274

[引用 userid="7882" URL"~/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/1048751/msp430fr2633-regarding-codegen-274 ]]编写以下链接时，编译器错误会发生什么类型的 C 代码？

/*

cl430 -vmspx --code_model=large --data_model=large --near_data=globals --opt_level=off test.c -k --symdebug:none -z -llnkx.cmd

*/

#include <stdio.h>

void func(void) { }
void call1(void) { }

int something;

void fn1()
{
    if ((unsigned)(unsigned long)func & 1) call1();
}

void fn2()
{
    if ((unsigned)(unsigned long)&something & 1) call1();
}

int main()
{
    fn1();
    fn2();
    return 0;
}

当此代码的构建如注释中开头附近所示时，会发生...

% cl430 -vmspx --code_model=large --data_model=large --near_data=globals --opt_level=off test.c -k --symdebug:none -z -llnkx.cmd
