.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 section .global symbol, .globl symbol), so is normally
not visible to ld.
The syntax for .lcomm differs slightly on the HPPA. The syntax is
`symbol .lcomm, length'; symbol is optional.
