Subject: [PATCH 3/3] reed_solomon: Fix array subscript 0 is outside array
|
||
|
|
bounds
|
||
|
|
|
||
|
|
The grub_absolute_pointer() is a compound expression that can only work
|
||
|
|
within a function. We are out of luck here when the pointer variables
|
||
|
|
require global definition due to ATTRIBUTE_TEXT that have to use fully
|
||
|
|
initialized global definition because of the way linkers work.
|
||
|
|
|
||
|
|
static gf_single_t * const gf_powx ATTRIBUTE_TEXT = (void *) 0x100000;
|
||
|
|
|
||
|
|
For the reason given above, use gcc diagnostic pragmas to suppress the
|
||
|
|
array-bounds warning.
