7.58 .lcomm symbol , length

Reserve length (an absolute expression) bytes for a local common denoted by symbol. The section and value of symbol are those of the new local common. The addresses are allocated in the bss section, so that at run-time the bytes start off zeroed. Symbol is not declared global (see .global), so is normally not visible to ld.

Some targets permit a third argument to be used with .lcomm. This argument specifies the desired alignment of the symbol in the bss section.

The syntax for .lcomm differs slightly on the HPPA. The syntax is `symbol .lcomm, length'; symbol is optional.
