/* If the .bss section's VMA is set to an address located before
|
|
|
|
the end of the .data section, causing the two sections to overlap,
|
|
|
|
return the overlap in bytes. Otherwise, return zero.
|
|
|
|
|
|
|
|
Motivation:
|
|
|
|
|
|
|
|
The GNU linker sometimes sets the start address of the .bss session
|
|
|
|
before the end of the .data section, making the 2 sections overlap.
|
|
|
|
The loader appears to handle this situation gracefully, by simply
|
|
|
|
loading the bss section right after the end of the .data section.
|
|
|
|
|
|
|
|
This means that the .data and the .bss sections are sometimes
|
|
|
|
no longer relocated by the same amount. The problem is that
|
|
|
|
the ldinfo data does not contain any information regarding
|
|
|
|
the relocation of the .bss section, assuming that it would be
|
|
|
|
identical to the information provided for the .data section
|
|
|
|
(this is what would normally happen if the program was linked
|
|
|
|
correctly).
|
|
|
|
|
|
|
|
GDB therefore needs to detect those cases, and make the corresponding
|
|
|
|
adjustment to the .bss section offset computed from the ldinfo data
|
|
|
|
when necessary. This function returns the adjustment amount (or
|
|
|
|
zero when no adjustment is needed). */
