performance libraries.
-xlinkopt (C)
This option instructs the compiler to
perform link-time optimization on the
resulting executable or dynamic library
over and above any optimizations in the
object files.
Warning issued by C compiler[
2]
-xloopinfo (C)
This option shows which loops are
paralleled and which are not.
Warning issued by C compiler[
2]
-xmemalign
This option specifies maximum assumed
memory alignment and behavior of
misaligned data accesses.
Warning issued by C compiler[
2]
-xMerge
This option merges data segments into text
segments.
Option ignored [
3]
-xopenmp
This option enables explicit parallelization
with OpenMP directives.
Warning issued by C compiler[
2]
-xpagesize
This option sets the preferred page size for
the stack and the heap.
Warning issued by C compiler[
2]
-xpagesize_heap
This option sets the preferred page size for
the heap.
Warning issued by C compiler[
2]
-xpagesize_stack
This option sets the preferred page size for
the stack.
Warning issued by C compiler[
2]
-xport64 (C++)
This option helps to debug code being
ported to a 64-bit environment.
Warning issued by C++
compiler[
1]
-xparallel (C)
This option parallelizes loops both
automatically by the compiler and
explicitly specified by the programmer.
Option ignored [
3]
-xprefetch
This option enables prefetch instructions on
those architectures that support prefetch.
Warning issued by C compiler[
2]
-xprefetch_level
This option controls the number of pre-fetch
instructions as determined with
-
xprefetch=auto
.
Warning issued by C compiler[
2]
-xprofile_ircache
This option is used with -
xprofile=collect,
or -
xprofile=use
to improve
compilation time during the use phase by
reusing compilation data saved from the
collect phase.
Warning issued by C compiler[
2]
-xprofile_pathmap
This option is used with -
xprofile=use
and it uses the prefix
of the UNIX pathname of a directory tree
in which object files were compiled.
Warning issued by C compiler[
2]
-xreduction (C)
This option turns on reduction recognition
during automatic parallelization.
Option ignored [
3]
-xregs
This option specifies the usage of registers
for the generated code.
Warning issued by C compiler[
2]
-xrestrict (C)
This option treats pointer-valued function
parameters as restricted pointers.
Option ignored [
3]
-xsafe=mem
This option enables the compiler to assume
no memory-based traps occur.
Option ignored [
3]
-xspace
This option passes the instruction to the
compiler to not do optimizations or
parallelization of loops that increase code
size.
Option ignored [
3]
