943edbd0d8 Nuke va-sh.h. stdarg.h and varargs.h now use __builtin_va_*. 2006-05-21 23:14:13 +00:00

9458b164a6 New stdarg.h and varargs.h based on arm and i386 versions. 
Use __builtin_va_* instead of hand written code in va-sh.h that uses
LHS casts.  Slightly worse code is generated by gcc 3.3.3, but LHS
casts are outlawed in gcc 3.3.6 and gcc 4.

Build-tested on hpcsh (le) and mmeye (be), run-tested on hpcsh.

d5b4b78d10 Change _BSD_VA_LIST_ from "void *" to "__builtin_va_list" for newer 
gcc versions and "char *" otherwise.  This is what most other arches
use, modulo different __GNUC_PREREQ__.

This is in preparation for replacing stdarg.h and varargs.h with
versions based on __builtin_* instead of handwritten code that gcc
3.3.6 and up refuse to compile b/c of lhs casts.

Identical binary code produced.

8572d2c144 Stop using linker scripts on all sh3 ports. 
The only information to be compensated is text section start address.
The default value is set arch-wise as DEFTEXTADDR.  Each kernel config
can override the default value by setting TEXTADDR.

Tested on COMPUTEXEVB (evbsh3).

61dd49d3bc Syscall debug tracing is handled by trace_enter() / trace_exit(). Change 
trace_is_enabled() to return TRUE if SYSCALL_DEBUG is defined, and g/c

routines.

be8b235384 Clean up fallout proc_is_traced_p() change: 
- proc_is_traced_p() -> trace_is_enabled(), to match trace_enter() and
  trace_exit().
- trace_is_enabled() becomes a real function.
- Remove unnecessary include files from various files that used to care
  about KTRACE and SYSTRACE, but do no more.

33c4e018e2 While here, shave off few bytes and few cycles off of the sh3_vector_tlbmiss. 
Since the registers we use are at the very end of address space, we
can load their addresses as small immediate negative constants instead
of loading them from memory.
