(lp#985904) + * enhancement: On SPARC, a limitation on the number of code constants + emittable by the compiler has been lifted, allowing certain long functions + to compiled and assembled which had previously been unsupported; fixes + cl-bench on this ISA (lp#1008996). + * optimization: On x86-64, code alignment of block headers is done with + multi-byte NOPs now instead of repetitions of the single-byte NOP. + * optimization: MAP-INTO is substantially faster when the target sequence is + of unknown type; mapping into lists is no longer O(N^2). (thanks to James + M. Lawrence) + * optimization: the compiler no longer heap-conses to check exits in cases + where the exit function is dynamic extent, or when it can prove the exit + function cannot escape. + * optimization: SB-SEQUENCE:DOSEQUENCE is faster on vectors of unknown + element type, and vectors that aren't SIMPLE-ARRAYs. + * bug fix: potential for infinite recursion during compilation of CLOS slot + typechecks when dependency graph had loops.

(lp#309467) + ** RANDOM on large integer arguments is generally faster and conses + less than before; this is visible for fixnums above a length of + about 24 bits, but extremely so for bignums: the old implementation + used time and space quadratical in the size of the argument there, + the new one is linear. + * enhancement: redesigned protocol for quitting SBCL. SB-EXT:EXIT is the new + main entry point, SB-EXT:QUIT is deprecated. + * enhancement: additions to the SB-THREAD API: RETURN-FROM-THREAD, + ABORT-THREAD, MAIN-THREAD-P, and MAIN-THREAD. + * enhancement: FASL loading no longer grabs the world-lock. + * enhancement: GENCGC reclaims space more aggressively when objects being + allocated are a large fraction of the total available heap space. + (lp#936304) + * enhancement: backtraces show the correct number of arguments for frames + called with too many arguments. + * enhancement: support for abort(3), exit(3), and _exit(2) has been added to + SB-POSIX. + * enhancement: ASDF has been updated 2.21. + * optimization: fewer uses of full calls to signed modular functions. + (lp#903821) + * optimization: typechecking alien values is typically 5 x faster. + * optimization: FDEFINITION, SYMBOL-FUNCTION, MACRO-FUNCTION, and FBOUNDP + are 20% faster. + * bug fix: file compilation performance issues when dumping subtypes + of CHARACTER (lp#994487) + * bug fix: fixed disassembly of some SSE instructions on x86-64. + * bug fix: SB-SIMPLE-STREAMS signals an error for bogus :CLASS arguments in + OPEN.
