* [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.
* Use tokenize() for splitting @cast's module listJosh Stone2009-04-211-7/+6

* NB @cast's relative header searchingJosh Stone2009-04-211-0/+14
|
* 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.
