f1ebb6136b reference: fix for reader's number grammar 2013-03-29 07:23:49 -06:00

17b8092641 extflonums 
An extflonum is like a flonum, but with 80-bit precision and
not a number in the sense of `number?': only operations such as
`extfl+' work on extflonums, and only on platforms where extflonums
can be implemented by hardware without interefering with flonums
(i.e., on platforms where SSE instructions are used for
double-precision floats).

[Patch provided by Michael Filonenko and revised by Matthew.]

The compiler tracks information about bindings that are known to
hold extflonums, but the JIT does not yet exploit this information
to unbox them (except as intermediate results).

9cf821b301 disallow #fx()' and #fl()' notation in `read-syntax' mode 
Allowing them would require support for immutable fxvectors and
flvectors, interning, and more. Since the motivation for reader
support is to make marshaling and unmarshaling easier, allow
them only in `read' mode. Change printing to make then unquotable.

060515b9cd extend string-literal syntax to allow surrogate-style \u pairs 
For example, "\uD834\uDD1E" is another way to write "\U01D11E",
while "\uD834", "\uDD1E" or "\uDD1E\uD834" are still errors.

ee775c3cc3 intern strings, etc. only when making syntax objects, not in `read' 
Rename `read-intern-literal' to `datum-intern-literal'.

Interning is needed only in `read-syntax' or `datum->syntax' to
set up the invariants that the bytecode compiler needs for cross-module
optimization. When `read'ing numbers from a data file, meanwhile,
interning slows things down a lot and doesn't seem worthwhile.

ec380e34ed remove built-in reader and printing support for Honu 
This is a backward-incompatible change, but I think it's
unlikely that any code depends on the removed bindings
or reader syntax.

6ac33a62be set `read-accept-lang' to #t by default, plus related adjustments 
including adding some uses of `with-module-read-parameterization'
 so that `read-accept-lang' is set right anyway; still, so many
 many places just set `read-accept-reader' to #t that making
 `read-accept-lang' #f by default looks like too big of an
 incompatibility
