Detailed Description

A basic block is a sequence of instructions with only one entry and
only one exit.  If any one of the instructions are executed, they
will all be executed, and in sequence from first to last.

There may be COND_EXEC instructions in the basic block.  The
COND_EXEC *instructions* will be executed -- but if the condition
is false the conditionally executed *expressions* will of course
not be executed.  We don't consider the conditionally executed
expression (which might have side-effects) to be in a separate
basic block because the program counter will always be at the same
location after the COND_EXEC instruction, regardless of whether the
condition is true or not.

Basic blocks need not start with a label nor end with a jump insn.
For example, a previous basic block may just "conditionally fall"
into the succeeding basic block, and the last basic block need not
end with a jump insn.  Block 0 is a descendant of the entry block.

A basic block beginning with two labels cannot have notes between
the labels.

Data for jump tables are stored in jump_insns that occur in no
basic block even though these insns can follow or precede insns in
basic blocks.   
Basic block information indexed by block number.
