[Qemu-devel] [PATCH v5 0/2] target-i386: define d r7 bit filed and change dr7 related functions

[liguang]

the breakpoint related functions are a little
hard to read for their implicit dr7 bit filed
and not well organized logic, so try to define
more readable bit filed for dr7 and clarify
the breakpoint logic.

changes v4->v5

- fix some not well formated changes.
- split functional and non-functional changes for cherry-picking
suggested by Andreas Färber <address@hidden>

changes v3->v4

- fix wrong logic of hw_{global,local}_breakpoint_enabled usage
suggested by Peter Maydell <address@hidden>

changes v2->v3

- split hw_breakpoint_enabled into hw_{global,local}_breakpoint_enabled

changes v1->v2

- add _TYPE_ to the name of dr7 bit field
- fix some coding styles
suggested by Peter Maydell <address@hidden>
