AIX Version 4.3 Assembler Language Reference
Makes a symbol globally visible to the linker.
The .globl pseudo-op makes the symbol Name globally visible to the linker and available to any file that is linked to the file in which the .globl pseudo-op occurs.
- If the .globl pseudo-op is not used for a symbol, then that symbol is, unless otherwise effected, only visible within the current assembly and not to other modules that may later be linked to the current assembly. Alternately, the .extern pseudo-op can be used to effect visibility.
- If Name is defined in the current assembly, its type and value arise from that definition, not the .globl definition.
- The binder maps all common segments with the same name into the same memory. If the name is declared .globl and defined in one of the segments, this has the same effect as declaring the common symbols to be .globl in all segments. In this way, common memory can be initialized.
|| Represents any label or symbol that is defined locally and requires external visibility. This parameter can be a Qualname. (A Qualname specifies a Name and StorageMappingClass for the control section.)|
The following example illustrates the use of the .globl pseudo-op:
The .comm pseudo-op, .extern pseudo-op.
