SYNOPSIS
- static int locval (char *loc)
+ static int locval (struct dieinfo *dip)
DESCRIPTION
Given pointer to a string of bytes that define a location, compute
the location and return the value.
A location description containing no atoms indicates that the
- object is optimized out. The global optimized_out flag is set for
- those, the return value is meaningless.
+ object is optimized out. The optimized_out flag is set for those,
+ the return value is meaningless.
When computing values involving the current value of the frame pointer,
the value zero is used, which results in a value relative to the frame
pointer, rather than the absolute value. This is what GDB wants
anyway.
- When the result is a register number, the global isreg flag is set,
- otherwise it is cleared. This is a kludge until we figure out a better
+ When the result is a register number, the isreg flag is set, otherwise
+ it is cleared. This is a kludge until we figure out a better
way to handle the problem. Gdb's design does not mesh well with the
DWARF notion of a location computing interpreter, which is a shame
because the flexibility goes unused.
