| * PR 9941: Add predicate function callback to check for an early abortRajan Arora2009-04-223-2/+12
| | | | | | | | | | | | | | * tapsets.cxx: Add dwfl_report_offline_predicate to check pending interrupts for an early abort. * tapsets.h: Declare it. * translate.cxx: Add callback to function call.
| * Make sdt.h big endian aware.Stan Cox2009-04-222-15/+15
| | | | | | | | | | | | * sdt.h: Use .quad instead of .long for .probe section addresses. ia64 and s390 require 'nop 0' and x86 tolerates it. * tapsets.cxx (build): Fetch probe_name in a big endian friendly fashion.
| * Correct sigmon.meta example title and name.Sunzen Wang2009-04-225-6/+6
| | | | | | | | | | | | | | | | * testsuite/systemtap.examples/process/sigmon.meta: Correct title and name. * testsuite/systemtap.examples/index.html: Regenerated. * testsuite/systemtap.examples/index.txt: Likewise. * testsuite/systemtap.examples/keyword-index.html: Likewise. * testsuite/systemtap.examples/keyword-index.txt: Likewise.
| * Simplify section size logic.Mark Wielaard2009-04-221-5/+1
| | | | | | | | | | | | * translate.cxx (dump_unwindsyms): Just check that dwfl_module_relocations() return more than 1 relocation section bases before calling dwfl_module_address_section().
| * [tracepoints] Resolve implicit trace_X useJosh Stone2009-04-211-1/+2
| | | | | | | | | | | | | | Some of the tracepoints are actually being called in inlines in the common headers (e.g. trace_kmalloc), which is causing errors about implicit function declarations. We don't care about ever running the code in the tracequery module, so I'm just suppressing that error.
| * [tracepoints] Don't use TRACE_HEADER_MULTI_READJosh Stone2009-04-211-4/+0
| | | | | | | | | | | | | | At one point that macro was needed to get all of the tracepoints on the tip tree, but now it's causing us to get duplicate stapprobe_X definitions. AFAICS, we're now getting all tracepoints even without MULTI_READ, so I'm pulling that workaround out.

| |
| * Refine the @cast-with-header syntaxJosh Stone2009-04-215-25/+45
| | | | | | | | | | | | | | The special syntax to generate a module for type information is now: - "kernel<path/to/header.h>" to use the kernel's build environment - "<path/to/header.h>" to use no special build environment, and so use gcc's default parameters only (for user mode).
| * Set MAXSTRINGLEN to 133 for uprobes_ustack.exp test on 64 bit.Mark Wielaard2009-04-211-1/+4
| | | | | | | | | | | | | | | | Needs extra space since on 64bit the last ubacktrace string is 7 entries * (16 hex + 2 for 0x + 1 space) = 133 chars. Default MAXSTRINGLEN is 128 chars. * testsuite/systemtap.base/uprobes_ustack.exp: Add -DMAXSTRINGLEN.

| * | PR10055: generate dummy modules w/ types for @castJosh Stone2009-04-201-0/+56
| | | | | | | | | | | | | | | | | | | | | The module field in @cast can now also be "kmod<path/to/header.h>" or "umod<path/to/header.h>" to generate a kernel or user module which includes the specified header. The appropriate compiler flags are used to save all possible type debuginfo from the header.
| * | Suppress module-loading errors in @castsJosh Stone2009-04-201-1/+10
| | | | | | | | | | | | | | | | | | If a @cast encounters a module that it can't load, it should just go on to the next module instead of throwing an exception. If there is no next module, we'll get a better "type not found" exception anyway.
