fixes to PPC version of cas(), from David Kirkman <dkirkman@gmail.com>

From David's email:
The problem is that the inline assembler code was placing the result
of an operation in a register that is used as input later in the code.
At the bottom of this message I've extracted a short short code
fragment that you can run through gcc (on a powerpc machine) to see
the generated assembly output.

The changes to fix the problem are fairly simple.  The first adds an
ampersand to the output list of the assembly fragment ("=r" (result)
--> "=&r" (result)) The ampersand just tells gcc that result can not
be placed in a register used for any of the input parameters (o, n, or
p).  Otherwise, it feels free to place output parameters in the same
registers used by the inputs -- but because of the flow of control
here we need everything in a distinct register.  This change fixes the
TVar program above.

The second change adds a clobber list (the :"cc", "memory").  This
tells gcc that the condition code (due to the compare) and memory (due
to the store) might be changed during the asm execution.  The lack of
a clobber list did not seem to be causing any trouble, but without it
gcc is free to assume that no state is changed during the execution.

Fall over more gracefully when there's a Template Haskell error

For a long time, Template Haskell has fallen over in a very un-graceful
way (i.e. panic) even when it encounters a programmer error.  In particular,
when DsMeta converts HsSyn to TH syntax, it may find Haskell code that
TH does not understand. This should be reported as a normal programmer
error, not with a compiler panic!

Originally the desugarer was supposed to never generate error
messages, but this TH desugaring thing does make it do so.  And in
fact, for other reasons, the desugarer now uses the TcRnIf monad, the
common monad used by the renamer, typechecker, interface checker, and
desugarer.

This patch completes the job, by
 - allowing the desugarer to generate errors
 - re-plumbing the error handling to take account of this
 - making DsMeta use the new facilities to report error gracefully

17 years agoDo not repeatedly simplify an argument more than once
simonpj@microsoft.com [Thu, 10 Aug 2006 14:15:26 +0000 (14:15 +0000)]
Do not repeatedly simplify an argument more than once

A very important invariant of the simplifier is that we do not simplify
an arbitrarily large expression more than once in a single pass. If this
can happen, then we can get exponential behaviour, when the large expression
itself has a large sub-expression which is simplified twice, and so on.

GHC has a long-standing bug which allows this repeated simplification to
happen.  It shows up when we have a function like this

f d BIG
where f's unfolding looks like
\x -> case x of (a,b) -> a
Of course this is v common for overloaded functions.

Before this patch we simplified all the args (d and BIG) before
deciding to unfold f.  Then we push back the simplified BIG onto the
continuation stack, inline f, so now we have
(case d of (a,b) -> a) BIG
After we reduce the case a bit, we'll simplify BIG a second time.  And
that's the problem.

The quick-and-dirty solution is to keep a flag in the ApplyTo continuation
to say whather the arg has already been simplified.  An alternative would
be to simplify it when first encountered, but that's a bigger change.

This looks to me like a long-standing bug. simplNonRecX was calling
preInlineUnconditionally, even though it was given an already-simplified
expression.  Exponential behaviour beckons.
