#### 9.16.2 x86 specific Directives

`.lcomm symbol , length[, alignment]`

  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. Since symbol is not declared global, it is normally not visible to `ld`. The optional third parameter, alignment, specifies the desired alignment of the symbol in the bss section.

  This directive is only available for COFF based x86 targets.

`.largecomm symbol , length[, alignment]`

  This directive behaves in the same way as the `comm` directive except that the data is placed into the .lbss section instead of the .bss section Comm.

  The directive is intended to be used for data which requires a large amount of space, and it is only available for ELF based x86_64 targets.

`.value expression [, expression]`

  This directive behaves in the same way as the `.short` directive, taking a series of comma separated expressions and storing them as two-byte wide values into the current section.
