[Bug c/23618] New: GCC seems to generate line number information for the same line in two places

2005-08-29 Thread tommi dot hoynalanmaa at iki dot fi 
When compiling a function with an empty body, e.g.
  int MyFunc(void)
{
}
GCC seems to add line number information for the line containing the opening
bracket in two different places. 

Here is an example assembler output:

.globl MyFunc
.type   MyFunc, @function
MyFunc:
.LFB3:
.loc 1 5 0
pushl   %ebp
.LCFI0:
movl%esp, %ebp
.LCFI1:
.loc 1 5 0
popl%ebp
ret
.LFE3:

Line number information for line 5 (the opening bracket) is seems to be added in
two places.
