Reid Spencer cf7ebf5cef Update documentation for parameter attributes for the syntax change. 
llvm-svn: 33238
 2007-01-15 18:27:39 +00:00
Chris Lattner c0f423a452 Terminology change: drop 'integral' completely. Now we just have integer, 
which includes i1.  Change the semantics of the various instructions to
support i1 where they didn't before: for example, it is now legal [though
not terribly useful, as it is the same as xor] to add two i1 values.

Reid Spencer b4f9a6f110 For PR411: 
This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
  llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
  llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
  llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
  llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
  llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.

Andrew Lenharth 5fb787c619 OK, after checking the backwards compatibility code on X86 and the new code 
path on alpha, now has come the time for new vararg support.  So, with out
further ado, I revert behavior back a couple of years!

Well, ok, I lied.  A few more notes.

First, the Simple ISels cannot be expected to work any longer, but they
should still compile

Second, there are likely some bugs to track down once the nightly testers
start with this.

Third, the initial patch doesn't include sparcv9, but I'll do that today.

Forth, subsequent patches won't bother being long winded.

Chris Lattner 6a4a0492f8 Patch contributed by Patrick Meredith: 
added notes on the fact that the current implementation uses
sbyte* for va_list.  Updated all occurances of valist to va_list (it was
inconsistant and find/replace is so easy ;-) ).  Added <...> around all
occurances of va_list in the intrinsic functions to match the vaarg and
vanext instructions and to further show that va_list is a variable type.

John Criswell 7a57647f97 Corrected the descriptions of the llvm.writeport and llvm.writeio 
intrinsics.

Modified llvm.readio and llvm.writeio to use pointers to memory instead
of integers.  This should take care of problems such as different pointer
sizes, casting integers to pointers, weird architectural pointer types, etc.

Re-worded the description of llvm.readio and llvm.writeio so that it should
be more clear as to why they should be used over regular loads/stores for
I/O.

so that they do not specify specific integer sizes (as those are
constrained by the code generator, not the intrinsic itself).

Also put these intrinsics into their own "Operating System" section.
