; The reason for the bug was that when deciding if a global
|
|
; variable can be part of sdata, we were wrongly ignoring
|
|
; the presence of any section specified for the variable
|
|
; using the section attribute. If such a section is specified,
|
|
; and that section is not sdata*/sbss* then the variable
|
|
; cannot use GPREL addressing, i.e. memw(#variablename).
