Boostc: Union Size Is Too Large

[thiemann 0]

Bug description:

The BoostC compiler is making unions tool large. It makes them the same size

as a structure.

 

Steps to reproduce:

1.) Create a new project

2.) Add a main.c file to the project with the following code

union TEST
{
  int x1;
  int x2;
  int x3;
  int x4;
  int x5;
};

union TEST w;


void main()
{

}

 

3.) Compile and link the project using BoostC

4.) Notice the compiler reports that 10 bytes of RAM are used when only 2 bytes should be used.

 

Expected behavior:

Only 2 bytes of RAM should be used.

 

Is the problem 100% reproducible:

Yes

 

SourceBoost version: 5.7

Compiler: BoostC

Compiler version: 1.7 Alpha

 

OS: Windows XP

thiemann,

 

I have had a look at this one.

Quite right there is a problem here - looks like compiler is generating wrong size for this new data type - so I'm in the clear on this as I only work on linker, its a little job for Pavel
