2005-05-30 Frank Ch. Eigler More fully parse & elaborate "expr in array" construct. * staptree.h (array_in): Make this unary. Update .cxx to match. * parse.cxx (parse_array_in): Rewrite. (parse_symbol_plain): Removed. Update .h to match. * elaborate.cxx (typeresolution_info::visit_array_in): New function. (find_array): Tentatively, accept arity=0. * translate.cxx (c_unparser::c_assign): New functions to eliminate much ugly duplication. Use throughout. (visit_symbol): Correct function formal argument search. (c_tmpcounter*::visit): Add missing recursion in several functions. * testsuite/*: Add new tests for array-in construct. Add the first "transok" test. * Makefile.am: Add transok tests. * Makefile.in: Regenerated. 2005-05-26 Frank Ch. Eigler * translate.cxx: Traverse trees just for common-header generation, to emit explicit temp variables into context. Switch to explicit "frame" pointer in generated function/probe bodies. Initialize locals in function bodies. Rename "test_unparser" to "c_unparser" throughout. 2005-05-24 Frank Ch. Eigler * elaborate.cxx (find_array): Support automagic tapset globals. * testsuite/semok/nine.stp: Test it. * staptree.cxx (stapfile print): List globals. 2005-05-24 Frank Ch. Eigler * testsuite/semlib/*: New tapset library chunks for "-I" testing. * testsuite/semok/eight.stp, nine.stp: New tests. 2005-05-22 Frank Ch. Eigler * Makefile.am (gcov): New target to generate test-coverage data from a testsuite run. * Makefile.in: Regenerated. 2005-05-20 Frank Ch. Eigler Many changes throughout. Partial sketch of translation output. * elaborate.*: Elaboration pass. * translate.*: Translation pass. * staptree.*: Simplified for visitor concept. * main.cxx: Translator mainline. * *test.cxx: Removed. * testsuite/*: Some new tests, some changed for newer syntax. 2005-05-05 Frank Ch. Eigler * parse.cxx (parse): Add helper methods. (lexer::scan, parse_assignment): Parse "<<<" operator. Fix assignment associativity. (parse_symbol): Permit function with empty arg list. (parse_global, parse_statement, parse_functiondecl): Expect unconsumed leading keyword. (parse_global): Don't use ";" termination. * parse.h: Corresponding changes. * staptree.cxx (binary_expression::resolve_types): Fix <<< type inference. (translator_output): Improve pretty-printing. (*): Add general visitors to statement/expression types. * staptree.h: Corresponding changes. Tweak symresolution_info fields. Add semantic_error class. * semtest.cxx: Adapt to this. * testsuite/parseok/two.stp, semok/*.stp: Adapt to syntax changes. 2005-03-15 Frank Ch. Eigler * semtest.cxx: Print probe signatures properly. * staptree.cxx (probe::printsig): New function. 2005-03-15 Frank Ch. Eigler * TODO: New file. Include some probe-point-provider syntax examples. * parse.cxx (lexer::scan, parser::parse_literal): Support hex, octal numbers via strtol. (parse_probe, parse_probe_point): Modify for dotted syntax. * staptree.cxx: Ditto. * parsetest.cxx, semtest.cxx: Print parse/sem results even if .stp files were given on command line. * parse.h, staptree.h: Rename probe_point_spec -> probe_point. * runtest.sh: New test-runner front-end script. * Makefile.am: Use it for TESTS_ENVIRONMENT. * testsuite/*: Update probe point syntax. Add a bunch of new tests. 2005-03-04 Frank Ch. Eigler * parse.cxx (scan): Support '$' characters in identifiers. (parse_symbol): Support thread-> / process-> shorthand. * staptree.cxx (symresolution_info::find): Split up into find_scalar, find_array, find_function. (resolve_symbols): Call the above for symbol/arrayindex/functioncall. (find_scalar): Add stub support for synthetic builtin variables. * staptree.h: Corresponding changes. * testsuite/*: Some new tests. 2005-03-03 Frank Ch. Eigler * parse.cxx (parse_assignment): Assert lvalueness of left operand. * staptree.h (expression): Add is_lvalue member. * staptree.cxx (functioncall::resolve_types): Don't crash on formal-vs-actual argument count mismatch. (*): Add some is_lvalue stub functions. * testsuite/*: Some new tests. 2005-03-01 Frank Ch. Eigler * parse.cxx: Implement left-associativity for several types of operators. Add some more statement types. Parse functions. Be able to print tokens. Simplify error generating functions. Save tokens in all parse tree nodes. * parse.h: Corresponding changes. * staptree.cxx: Move tree-printing functions here. Add many new functions for symbol and type resolution. * staptree.h: Corresponding changes. * semtest.cxx: New semantic analysis pass & test driver. * testsuite/sem*/*: New tests. * parsetest.cxx: Separated parse test driver. * testsuite/parse*/*: Adapt tests to parsetest driver. * Makefile.am: Build semtest. Run its tests. * Makefile.in: Regenerated. 2005-02-11 Frank Ch. Eigler * parse.cxx, parse.h: New files: parser. * staptree.h: New file: semantic object declarations. * staptree.cxx: New dummy driver file.
