#define HISTFRACTION 2
/* Fraction of text space to allocate for from hash buckets.
The value of HASHFRACTION is based on the minimum number of bytes
of separation between two subroutine call points in the object code.
Given MIN_SUBR_SEPARATION bytes of separation the value of
HASHFRACTION is calculated as:
HASHFRACTION = MIN_SUBR_SEPARATION / (2 * sizeof (short) - 1);
For example, on the VAX, the shortest two call sequence is:
calls $0,(r0)
calls $0,(r0)
which is separated by only three bytes, thus HASHFRACTION is
calculated as:
HASHFRACTION = 3 / (2 * 2 - 1) = 1
Note that the division above rounds down, thus if MIN_SUBR_FRACTION
is less than three, this algorithm will not work!
In practice, however, call instructions are rarely at a minimal
distance. Hence, we will define HASHFRACTION to be 2 across all
architectures. This saves a reasonable amount of space for
profiling data structures without (in practice) sacrificing
any granularity. */
#define HASHFRACTION 2
/* Percent of text space to allocate for tostructs.
This is a heuristic; we will fail with a warning when profiling
programs with a very large number of very small functions, but
that's normally OK.
2 is probably still a good value for normal programs.
Profiling a test case with 64000 small functions will work if
you raise this value to 3 and link statically (which bloats the
text size, thus raising the number of arcs expected by the heuristic). */

syscalls.c : Newlib operating system interface
========================================================================
This is the maven implementation of the narrow newlib operating
system interface. It is based on the minimum stubs in the newlib
documentation, the error stubs in libnosys, and the previous scale
implementation. Please do not include any additional system calls or
other functions in this file. Additional header and source files
should be in the machine subdirectory.
Here is a list of the functions which make up the operating system
interface. The file management instructions execute syscall assembly
instructions so that a proxy kernel (or the simulator) can marshal up
the request to the host machine. The process management functions are
mainly just stubs since for now maven only supports a single process.
- File management functions
+ open : (v) open file
+ lseek : (v) set position in file
+ read : (v) read from file
+ write : (v) write to file
+ fstat : (z) status of an open file
+ stat : (z) status of a file by name
+ close : (z) close a file
+ link : (z) rename a file
+ unlink : (z) remote file's directory entry
- Process management functions
+ execve : (z) transfer control to new proc
+ fork : (z) create a new process
+ getpid : (v) get process id
+ kill : (z) send signal to child process
+ wait : (z) wait for a child process
- Misc functions
+ isatty : (v) query whether output stream is a terminal
+ times : (z) timing information for current process
+ sbrk : (v) increase program data space
+ _exit : (-) exit program without cleaning up files
There are two types of system calls. Those which return a value when
everything is okay (marked with (v) in above list) and those which
return a zero when everything is okay (marked with (z) in above
list). On an error (ie. when the error flag is 1) the return value is
always an errno which should correspond to the numbers in
newlib/libc/include/sys/errno.h
