static and global variables allocation

static and global variables allocation

[PhDUCSB]

I want to know which files in the gcc compiler deals with static and global
variable allocations because I would like to change the place they are
allocated at in memory. Any help would be appreciated. Thanks,

They are handled in gcc/varasm.c.  However, if what you care about is
where they wind up in memory, then you probably don't want to fiddle
with gcc.  It is the linker which lays variables out in memory.  One
approach is to group variables into sections using the section
attribute.  Then use a linker script to put the sections at the
addresses you want.
