emulate_branch(3)					     Library Functions Manual						 emulate_branch(3)

Name
       emulate_branch, execute_branch - branch emulation

Syntax
       #include <signal.h>

       emulate_branch(scp, branch_instruction)
       struct sigcontext *scp;
       unsigned long branch_instruction;

       execute_branch(branch_instruction)
       unsigned long branch_instruction;

Description
       The  function  is  passed  a signal context structure and a branch instruction.	It emulates the branch based on the register values in the
       signal context structure.  It modifies the value of the program counter in the signal context  structure  (sc_pc)  to  the  target  of  the
       branch_instruction.   The program counter must initially be pointing at the branch and the register values must be those at the time of the
       branch.	If the branch is not taken the program counter is advanced to point to the instruction after the delay slot (sc_pc += 8).

       If the branch instruction is a `branch on coprocessor 2' or `branch on coprocessor 3' instruction, calls to  execute  the  branch  in  data
       space to determine if it is taken or not.

Return Values
       The  function returns a 0 if the branch was emulated successfully.  A non-zero value indicates the value passed as a branch instruction was
       not a branch instruction.

       The function returns non-zero on taken branches and zero on non-taken branches.

Restrictions
       Since is only intended to be used by it does not check its parameter to see if in fact it is a branch instruction.  It is really a stop gap
       in case a coprocessor is added without the kernel fully supporting it (which is unlikely).

NAME

       archpath - output arch (tla/Bazaar) archive names, with support for branches

SYNOPSIS

       archpath
       archpath branch
       archpath branch--version

DESCRIPTION

       archpath is intended to be run in an arch (tla or Bazaar) working copy.

       In its simplest usage, archpath with no parameters outputs the package name (archive/category--branch--version) associated with the working
       copy.

       If a parameter is given, it may either be a branch--version, in which case archpath will output a corresponding package name in the current
       archive and category, or a plain branch name (without '--"), in which case archpath will output a corresponding package name in the current
       archive and category and with the same version as the current working copy.

       This is useful for branching.  For example, if you're using Bazaar and you want to create a branch for a new feature, you might use a  com-
       mand like this:

              baz branch $(archpath) $(archpath new-feature)

       Or if you want to tag your current code onto a 'releases' branch as version 1.0, you might use a command like this:

              baz branch $(archpath) $(archpath releases--1.0)

       That's much easier than using 'baz tree-version' to look up the package name and manually modifying the result.
