The driver routine for the compiler is dt_compile(), below. The 347c478bd9Sstevel@tonic-gate * compiler operates on either stdio FILEs or in-memory strings as its input 357c478bd9Sstevel@tonic-gate * and can produce either dtrace_prog_t structures from a D program or a single 367c478bd9Sstevel@tonic-gate * dtrace_difo_t structure from a D expression. Multiple entry points are 377c478bd9Sstevel@tonic-gate * provided as wrappers around dt_compile() for the various input/output pairs. 387c478bd9Sstevel@tonic-gate * The compiler itself is implemented across the following source files: 397c478bd9Sstevel@tonic-gate * 407c478bd9Sstevel@tonic-gate * dt_lex.l - lex scanner 417c478bd9Sstevel@tonic-gate * dt_grammar.y - yacc grammar 427c478bd9Sstevel@tonic-gate * dt_parser.c - parse tree creation and semantic checking 437c478bd9Sstevel@tonic-gate * dt_decl.c - declaration stack processing 447c478bd9Sstevel@tonic-gate * dt_xlator.c - D translator lookup and creation 457c478bd9Sstevel@tonic-gate * dt_ident.c - identifier and symbol table routines 467c478bd9Sstevel@tonic-gate * dt_pragma.c - #pragma processing and D pragmas 477c478bd9Sstevel@tonic-gate * dt_printf.c - D printf() and printa() argument checking and processing 487c478bd9Sstevel@tonic-gate * dt_cc.c - compiler driver and dtrace_prog_t construction 497c478bd9Sstevel@tonic-gate * dt_cg.c - DIF code generator 507c478bd9Sstevel@tonic-gate * dt_as.c - DIF assembler 517c478bd9Sstevel@tonic-gate * dt_dof.c - dtrace_prog_t -> DOF conversion 527c478bd9Sstevel@tonic-gate * 537c478bd9Sstevel@tonic-gate * Several other source files provide collections of utility routines used by 547c478bd9Sstevel@tonic-gate * these major files. The compiler itself is implemented in multiple passes: 557c478bd9Sstevel@tonic-gate * 567c478bd9Sstevel@tonic-gate * (1) The input program is scanned and parsed by dt_lex.l and dt_grammar.y 577c478bd9Sstevel@tonic-gate * and parse tree nodes are constructed using the routines in dt_parser.c. 587c478bd9Sstevel@tonic-gate * This node construction pass is described further in dt_parser.c. 597c478bd9Sstevel@tonic-gate * 607c478bd9Sstevel@tonic-gate * (2) The parse tree is "cooked" by assigning each clause a context (see the 617c478bd9Sstevel@tonic-gate * routine dt_setcontext(), below) based on its probe description and then 627c478bd9Sstevel@tonic-gate * recursively descending the tree performing semantic checking. The cook 637c478bd9Sstevel@tonic-gate * routines are also implemented in dt_parser.c and described there. 647c478bd9Sstevel@tonic-gate * 657c478bd9Sstevel@tonic-gate * (3) For actions that are DIF expression statements, the DIF code generator 667c478bd9Sstevel@tonic-gate * and assembler are invoked to create a finished DIFO for the statement. 677c478bd9Sstevel@tonic-gate * 687c478bd9Sstevel@tonic-gate * (4) The dtrace_prog_t data structures for the program clauses and actions 697c478bd9Sstevel@tonic-gate * are built, containing pointers to any DIFOs created in step (3). 707c478bd9Sstevel@tonic-gate * 717c478bd9Sstevel@tonic-gate * (5) The caller invokes a routine in dt_dof.c to convert the finished program 727c478bd9Sstevel@tonic-gate * into DOF format for use in anonymous tracing or enabling in the kernel. 737c478bd9Sstevel@tonic-gate * 747c478bd9Sstevel@tonic-gate * In the implementation, steps 2-4 are intertwined in that they are performed 757c478bd9Sstevel@tonic-gate * in order for each clause as part of a loop that executes over the clauses. 767c478bd9Sstevel@tonic-gate * 777c478bd9Sstevel@tonic-gate * The D compiler currently implements nearly no optimization. The compiler 787c478bd9Sstevel@tonic-gate * implements integer constant folding as part of pass (1), and a set of very 797c478bd9Sstevel@tonic-gate * simple peephole optimizations as part of pass (3). As with any C compiler, 807c478bd9Sstevel@tonic-gate * a large number of optimizations are possible on both the intermediate data 817c478bd9Sstevel@tonic-gate * structures and the generated DIF code. These possibilities should be 827c478bd9Sstevel@tonic-gate * investigated in the context of whether they will have any substantive effect 837c478bd9Sstevel@tonic-gate * on the overall DTrace probe effect before they are undertaken. 847c478bd9Sstevel@tonic-gate */ 857c478bd9Sstevel@tonic-gate 867c478bd9Sstevel@tonic-gate #include <sys/types.h> 877c478bd9Sstevel@tonic-gate #include <sys/wait.h> 887c478bd9Sstevel@tonic-gate 897c478bd9Sstevel@tonic-gate #include <assert.h> 907c478bd9Sstevel@tonic-gate #include <strings.h> 917c478bd9Sstevel@tonic-gate #include <signal.h> 927c478bd9Sstevel@tonic-gate #include <unistd.h> 937c478bd9Sstevel@tonic-gate #include <stdlib.h> 947c478bd9Sstevel@tonic-gate #include <stdio.h> 957c478bd9Sstevel@tonic-gate #include <errno.h> 967c478bd9Sstevel@tonic-gate #include <ucontext.h> 977c478bd9Sstevel@tonic-gate #include <limits.h> 987c478bd9Sstevel@tonic-gate #include <ctype.h> 997c478bd9Sstevel@tonic-gate #include <dirent.h> 1007c478bd9Sstevel@tonic-gate #include <dt_module.h> 1011a7c1b72Smws #include <dt_program.h> 1027c478bd9Sstevel@tonic-gate #include <dt_provider.h> 1037c478bd9Sstevel@tonic-gate #include <dt_printf.h> 1047c478bd9Sstevel@tonic-gate #include <dt_pid.h> 1057c478bd9Sstevel@tonic-gate #include <dt_grammar.h> 1067c478bd9Sstevel@tonic-gate #include <dt_ident.h> 1077c478bd9Sstevel@tonic-gate #include <dt_string.h> 1087c478bd9Sstevel@tonic-gate #include <dt_impl.h> 1097c478bd9Sstevel@tonic-gate 1107c478bd9Sstevel@tonic-gate static const dtrace_diftype_t dt_void_rtype = { 1117c478bd9Sstevel@tonic-gate DIF_TYPE_CTF, CTF_K_INTEGER, 0, 0, 0 1127c478bd9Sstevel@tonic-gate };
