4f23ce577c Ported SBCL's FLONUM-TO-STRING to ECL's core (in C). 
New function INTEGER-TO-STRING added to ECL's core.
Both FLOAT-TO-STRING and INTEGER-TO-STRING are used in ECL's printer.
FORMAT uses ECL's new FLOAT-TO-STRING.

03049ee7e2 Make boxed SSE packs untyped for all purposes but printing. 
Now the following rules hold:

- (type-of pack) = SSE-PACK
- (typep pack '*-SSE-PACK) = T

The compiler is tweaked to unbox unidentified packs as
__m128i (integer), assuming that a cast would be inserted
later if that is not what was needed.

c4dd32ca96 Third iteration at the problem with packages_to_be_created. Now this variable is associated to a flag that deactivates its use outside read_VV's reader. 2010-09-05 22:43:49 +02:00

5c63cd8345 When compiling for the Windows API, define ECL_MS_WINDOWS_HOST instead of checking for mingw or _MSC_VER separately (Gabriel Dos Reis) 2010-08-22 22:29:21 +02:00

b9b648e16e The default rehash size and threshold are now static constants. 2010-08-21 11:53:33 +02:00

8ed8a8e807 Add a function for retrieving the array element size in bytes. 
This information is necessary for various alignment needs and
other low-level memory manipulation. For bit it returns a ratio.

7c7a40e4bd Add a function for computing the pointer to a row-major-aref item. 
This is necessary for open-coding the actual array access, while
keeping the array object type and index bound check. The array
element type is not checked; instead the function ensures that the
specified number of bytes at the returned ptr are within bounds.

5088dd10b5 Implement compilation of SSE packed vector constants. 
The constants are dumped as static C constants, with
data represented as integer byte values. This should
provide optimal performance and exact equality.

c348b6f948 Implement boxing and unboxing of SSE values in the compiler. 
This makes the SSE types marginally usable via c-inline:

(defun foo (xx yy)
  (let ((sum (ffi:c-inline
                 (xx yy) (:float-sse-pack :float-sse-pack)
                 :float-sse-pack
               "_mm_add_ps(#0,#1)" :one-liner t)))
    (ffi:c-inline (sum) (:float-sse-pack) :float-sse-pack
      "_mm_mul_ps(#0,_mm_set1_ps(3.0))" :one-liner t)))

ce2badff90 Add the boxed SSE packed vector types. 
Boxing SSE values is useless performance-wise, but necessary
to provide continuity between compiled and interpreted code.

This set of types is peculiar in that while the actual CPU
instruction set mostly does not care about the data types
(although mixing commands for ints and floats leads to
some performance degradation), the C intrinsic function
interface does distinguish the types to some extent.
Thus it also has to be represented in the ECL compiler.
