<div>
<pre>Given
.data
.global bar
.type bar, object
bar:
.long 42
.size bar, 4
.global zed
zed = bar + 1
gas produces
Symbol {
Name: zed (5)
Value: 0x1
Size: 4
Binding: Global (0x1)
Type: Object (0x1)
Other: 0
Section: .data (0x2)
}
and MC produces
Symbol {
Name: zed (5)
Value: 0x1
Size: 0
Binding: Global (0x1)
Type: None (0x0)
Other: 0
Section: .data (0x2)
}
Note that gas copies Size and Type and we don't.
gas allows type to be overridden, but not size.
I am not sure how much of this is a bug is gas and how much is a bug in MC. I
will report a bug on binutils to start a discussion.</pre>
