This script calculates the per-function absolute result count (EAFC) for the
|
|
"inject-on-write" fault model, which assumes that writes to memory can get
|
|
corrupted, and completely disregards storage duration (e.g. time between write
|
|
and subsequent read). The metric is calculated from the results of a normal
|
|
"inject-on-read" campaign, only using the FI results from memory accesses that
|
|
directly follow a "write" access.

# This implementation makes sure the write -- not the subsequent memory access
|
|
# that determines the result type -- happens in the context of the
|
|
# corresponding function.

#
|
|
# Currently does not take into account right-margin writes, i.e. those
|
|
# that are not followed by *any* memory access. This is mostly OK as
|
|
# import-trace creates synthetic 'write' events at the right margin for
|
|
# all but those memory accesses that are exactly on the right margin
|
|
# already.
