Stas Boukarev	8c81d9c770	Change the way FP zeros are handled in the type system. ... Do not put them into member types. Treat them like ordinary components of numeric-union-type, using -0.0 < 0.0 instead of -0.0 = 0.0. Now the only places where they have to be treated specially are generating type checks and printing type specifiers, which can share the same code.	2025-09-12 02:16:32 +03:00

Stas Boukarev	0dcf58ce89	Don't call lseek for each file-position. ... Call it only when a new buffer is filled.	2025-08-13 20:48:06 +03:00
Douglas Katzman	43af8c9253	Optimize out a few instructions in perfect hash calculation ... For sets of only character or only fixnum, there is no need to guard against an object having the wrong type. So instead of doing (if (fixnump x) (ldb ... x)) just use (ldb ... (get-lisp-obj-address x)) eliminating an initial branch. Also the AND operation - at least on x86-64 - avoids use of a raw constant. This just changes some shifts in the perfect hash expression. It drops a bit (or more) of precision, but we're already doing that in descriptor-hash32 for the situations where the keyset contains a mixture of immediates and symbols.	2025-07-07 18:28:54 +00:00
Douglas Katzman	7b3816c6b1	Transform typep on frozen structure unions	2025-06-30 20:47:29 +00:00
Douglas Katzman	1d6df61f23	x86-64: avoid a memory load when passing empty strings ... I discovered that over 2% of all code components in my application contain a pointer to the same 0-length string after coalescing. This change squeezes out the code header word (except for code compiled to memory)	2025-06-18 20:19:11 -04:00
Douglas Katzman	3d5139bef7	Use descriptor-hash32 only for a mixture of CASE key types ... Otherwise, just CHAR-CODE or just SYMBOL-NAME-HASH may be enough.	2025-06-17 00:42:43 +00:00
Douglas Katzman	21a23d809a	Use perfect hash more often in sequence transforms ... The ASSOC,MEMBER,etc functions were only handling symbols with perfect hashing. This change extends them to fixnum and character keys.	2025-06-16 20:07:45 +00:00
Douglas Katzman	ba509cda22	Implement DESCRIPTOR-HASH32 ... which is just like POINTER-HASH (removed at rev 1857b789) but with at most 32 significant bits of output. Fewer for some platforms. The vop reduces a multiway COND to an IF when computing the input to the perfect hash function in a CASE expression whose keys include {symbol|character|fixnum}. There's no need to test CHARACTERP or FIXNUMP, and 0 and #\null can both be keys of the same CASE because they hash differently now.	2025-06-16 19:52:00 +00:00
Stas Boukarev	a4248bd912	x86-64: better error handling from assembly routines.	2025-06-15 19:35:29 +03:00

Douglas Katzman	c5f93deeb9	Remove :linkage-cell-ud fixup flavor ... Storing an extra value at the patch point lets us avoid using 2 flavors	2025-05-07 21:11:43 -04:00
Douglas Katzman	3cc36fad5a	Regenerate xoerfecthash files	2025-05-02 13:47:00 +00:00
Douglas Katzman	e8c3444d6c	Remove :alien-{code,data}-linkage-index fixup flavors ... :foreign[-dataref] are enough, though we need different techniques to apply the fixup depending on immobile code or not. This "should" be captured in the KIND of fixup, but it's disappointingly tricky to adapt the assembler to different kinds with the same flavor. I'm also annoyed that this adds more logic to the disassembler, however, the change resolves a problem cited in the comment above FOREIGN-SYMBOL-SAP - the linkage stub should entail a yieldpoint-based GC stop, which would not work if some uses of the entry rely on the abstraction leakage that "CALL [x+8]" is nearly the same as "CALL x".	2025-05-01 23:54:19 +00:00
Douglas Katzman	5c9841249d	Remove :symbol-value fixup flavor	2025-04-16 12:48:50 -04:00

Charles Zhang	f97a89306e	Resurrect breakpoint commands and breakpoint based stepping. ... The code for breakpoint commands in the debugger inherited from CMU CL was deleted in 8a8a892280, presumably because it was slightly broken on x86oids due to a constant being wrong. c7e96cb3045bc64179b9e81f266fb611aa67e1ac fixed that, so the breakpoint commands can be resurrected. The step command based on breakpoints has been included but under a different name because the single stepper exists now. All the functionality of the instrumentation based single stepper could likely be subsumed in the breakpoint based stepper without the instrumentation overhead, but for now let's have them coexist.	2025-03-07 20:44:00 +01:00
