# ---------

|
|
# Finds SSE41 support
|
|
#
|
|
# This module can be used to detect SSE41 support in a C compiler. If
|
|
# the compiler supports SSE41, the flags required to compile with
|
|
# SSE41 support are returned in variables for the different languages.
|
|
# The variables may be empty if the compiler does not need a special
|
|
# flag to support SSE41.
|
|
#
|
|
# The following variables are set:
|
|
#
|
|
# ::
|
|
#
|
|
# SSE41_C_FLAGS - flags to add to the C compiler for SSE41 support
|
|
# SSE41_FOUND - true if SSE41 is detected
|
|
#
