Summary: [MC assembler] does not support square bracket
notation
Product: new-bugs
Version: trunk
Platform: PC
OS/Version: FreeBSD
Status: NEW
Severity: normal
Priority: P
Component: new bugs

The MC assembler does not appear to support the following notation,
using square brackets, which occurs in some x86 assembly files:
.size x, [.-x]
Another example of this is used in FreeBSD, in combination with local
labels:
#define PIC_PROLOGUE \
pushl %ebx; \
call 1f; \
1: \
popl %ebx; \
addl $_GLOBAL_OFFSET_TABLE_+[.-1b],%ebx
As there is no reference at all in the gas documentation about this
'feature', I just looked in the source code instead...
It seems that only in case of ia64, square brackets are considered an
index operator (with unclear semantics, though). For most other cases,
they are equivalent with parentheses.
In binutils trunk, there is also an exception for i386, but only if gas
is using Intel syntax at that particular point in the file.
