Fix bit-/byte-offset mismatch in parameter to read_value_memory
|
|
|
|
The function read_value_memory accepts a parameter embedded_offset and
|
|
expects it to represent the byte offset into the given value. However,
|
|
the only invocation with a possibly non-zero embedded_offset happens in
|
|
read_pieced_value, where a bit offset is passed instead.
|
|
|
|
Adjust the implementation of read_value_memory to meet the caller's
|
|
expectation. This implicitly fixes the invocation in read_pieced_value.
|
|
|
|
gdb/ChangeLog:
|
|
|
|
* valops.c (read_value_memory): Change embedded_offset to
|
|
represent a bit offset instead of a byte offset.
|
|
* value.h (read_value_memory): Adjust comment.
