There is now one more + optimization round, and *opt-level* now goes up to 6 + rather than 7, 7 being the new default value. This + release makes 23 compiler commits. + + Bugs + + - Fixed incorrect scope in conda/condlet. + - Fixes for regressions preventing the source code of of + stdlib/ being used (.tl files, not .tlo), which is needed + for debugging some TXR problems. + - Fixed issue that happens when code is loaded that + generates warnings during error exception processing, + causing an "invalid re-entry of exception logic", + interfering with debugging TXR using an uncompiled + library (.tl files rather than .tlo). + - Fixed another issue using .tl files: interference + between library loading and the -C compat option. + Compatibility is temporarily disabled while + auto-loading. + - build macro: code rearranged to eliminate circular + dependency, preventing modules which depend on the macro + from loading. + - Pattern matching: ^#S() and ^H(()) quasiquote patterns + work now, thanks to a change in the parser. + - Compiler: + - Fixed incorrect evaluation order of function arguments + (when local variables are involved that are subject to + side effects during evaluation). + - Fixed issue with compiling defmacro: + - entire macro form was being retained + - yet errors not reported against the correct operator + name: e.g. (defstruct) says that defmacro has + insufficient arguments. + - fix also affects tree-bind and other operators. + - Fixes September 2022 regression in liveness + calculation, causing certain optimizations to be + forgone. + - Fixed incorrect blind register renaming across the + arguments of a close instruction, which are not + actually source operands of that instruction. + - Latent problem exposed when trying to replace V + register by T register more aggressively. + - Fixed incorrect live register calculation across catch + instruction. + - This has two clobber register operands. + - Representation of instruction live info was expanded + to handle two register defs. + + + TXR 285 2023-03-28 |
