* libdtrace: Permit taking the address of an identifier without type infoMark Johnston2025-07-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Symbols defined using assembler directives lack type info, but in this case one ought to be able to cast a pointer to the symbol and dereference the pointer to get a value. Without this change, D disallows this trick since it requires all identifiers to have a type. Relax the rules slightly and allow an identifier to have type "void" if we know we're just taking its address. As a result, the following dtrace invocation works: dtrace -n 'tick-1s {printf("%d", *(int *)&`ticks);}' In particular, since commit b2b974f7ef4c ("clock: Simplify subr_ticks and rename"), "ticks" does not have any type info associated with it, so its value couldn't be printed. This trick provides a workaround and is probably generally useful. Add a regression test which exercises this functionality.

* dtrace: Add the 'oformat' libdtrace optionDomagoj Stolfa2024-01-103-1/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This option can be used to specify a format to use in DTrace output. The following formats are supported: - json - xml - html - none (default DTrace output) This is implemented using libxo and integrated into libdtrace. Client code only works with the following API: - dtrace_oformat_setup(dtrace_hdl_t *) -- to be called when output is starting. - dtrace_oformat_teardown(dtrace_hdl_t *) -- to be called when output is finished - dtrace_oformat(dtrace_hdl_t *) -- check if oformat is enabled. - dtrace_set_outfp(FILE *) -- sets the output file for oformat. - Ensure that oformat is correctly checked in the drop handler and record processing callbacks. This commit also adds tests which check if the generated output is valid (JSON, XML) and extends the dtrace(1) describing the structured output.

* Enable creation of static userspace probes in incremental builds.Mark Johnston2020-08-201-4/+0
| | | | | | | | | | | | | | | | | | To define USDT probes, dtrace -G makes use of relocations for undefined symbols: the target address is overwritten with NOPs and the location is recorded in the DOF section of the output object file. To avoid link errors, the original relocation is destroyed. However, this means that the same input object file cannot be processed multiple times, as happens during incremental rebuilds. Instead, only set the relocation type to NONE, so that all information required to reconstruct USDT probes is preserved.
