config.gcc (tm_file): Prefix pa/pa-700.h to tm_file list for PA1.0 architecture and pa/pa-7100.h for... 

2002-05-30  John David Anglin  <dave@hiauly1.hia.nrc.ca>

	* config.gcc (tm_file): Prefix pa/pa-700.h to tm_file list for PA1.0
	architecture and pa/pa-7100.h for PA1.1 architecture, respectively.
	* pa/pa.c (override_options): Use TARGET_SCHED_DEFAULT to select
	default scheduling model.
	* pa/pa.h (TARGET_SCHED_DEFAULT): Define if not defined to "8000".
	* pa/pa-700.h (TARGET_SCHED_DEFAULT): New file for "700" scheduling.
	* pa/pa-7100.h (TARGET_SCHED_DEFAULT): New file for "7100" scheduling.
	* doc/install.texi (hppa*-*-*): Document default scheduling.

@ -1997,6 +1997,19 @@ If you wish to use pa-risc 2.0 architecture support, you must use either
the HP assembler, gas/binutils 2.11 or a recent
@uref{ftp://sources.redhat.com/pub/binutils/snapshots,,snapshot of gas}.
There are three default scheduling models for instructions. They
are PROCESSOR_700, PROCESSOR_7100 and PROCESSOR_8000. They are selected
based on the the pa-risc architecture specified for the target machine
when configuring. PROCESSOR_8000 is the default model. PROCESSOR_700
and PROCESSOR_7100 are selected by specifying either @samp{hppa1.0} or
@samp{hppa1.1}, respectively.
The PROCESSOR_8000 model is not well suited to older processors. Thus,
it is important to completely specify the machine architecture when
configuring if you want a model other than PROCESSOR_8000. The macro
TARGET_SCHED_DEFAULT can be defined in BOOT_CFLAGS if a different
default scheduling model is desired.
More specific information to @samp{hppa*-hp-hpux*} targets follows.
