           Summary: Cortex-m arch: hal_intr.h includes var_intr.h too
                    early.
           Product: eCos
           Version: 3.0
          Platform: All
        OS/Version: Cortex-M
            Status: UNCONFIRMED
          Severity: normal
          Priority: low
         Component: HAL
        AssignedTo: unassigned@bugs.ecos.sourceware.org
        ReportedBy: ilijak@siva.com.mk
                CC: ecos-bugs@ecos.sourceware.org
             Class: Advice Request


Created an attachment (id=1195)
 --> (http://bugs.ecos.sourceware.org/attachment.cgi?id=1195)
Include var_intr.h after definition of hal_intr.h macros but allows overriding
of CYGNUM_HAL_INTERRUPT_RTC.

In Cortex-M architecture, the header hal_intr.h includes var_intr.h twice.
Second one is of course with no effect, but the first one is too early. 
Namely some macros that are defined in hal_intr.h, such as
CYGNUM_HAL_INTERRUPT_EXTERNAL, are used in hal-intr.h. This doesn't seem to
show ill effect so far since usage is by other macros.

Note: The early inclusion of var_intr.h has been introduced by Bug 1001090
Attachment 1092 in order to enable overriding of CYGNUM_HAL_INTERRUPT_RTC by
variant/platform.

The proposed patch includes var_intr.h after definition of hal_intr.h macros
but also allows overriding of CYGNUM_HAL_INTERRUPT_RTC.

Thanks for catch. On my look CYGNUM_HAL_INTERRUPT_RTC definition became
misplaced lines via that request (no header, in fact). So, I would shift
down the definition and point on this on CL entry. Certainly, the first
inclusion of the header can be removed safely then.

Thanks for the reply Sergei. As far as I understand you are going to revert
hal_intr.h to state before Attachment 1092 and in addition shift
CYGNUM_HAL_INTERRUPT_RTC definition after inclusion of var_intr.h. Am I right?
It would fit, since var_intr.h shall be included after definition of Cortex-M
system vectors and before CYGNUM_HAL_INTERRUPT_RTC.

Right. Also, please, fix CL entry, as there is unsubjected mention of
CYGNUM_HAL_INTERRUPT_EXTERNAL.

OK - Could it be:
 ... after definition of
- CYGNUM_HAL_INTERRUPT_EXTERNAL
+ Cortex-M architecture common exception vectors

Ilija, I kept in mind something likes the below

* include/hal_intr.h: Place CYGNUM_HAL_INTERRUPT_RTC
cond. definition properly. Remove duplicated inclusion of
var_intr.h header.

Why do we need to talk about the exception vectors? As far as I could
understand CYGNUM_HAL_INTERRUPT_RTC definition is misplaced and there
is dup. header inclusion in hal_intr.h. So, you fix it and should add
record *about* it. Did I miss something?

Maybe I tried to be too descriptive. If we opt for short record I think the
main point is placing #include var_intr.h at right place so I would restate:

 * include/hal_intr.h: Remove double inclusion of var_intr.h header and include
   it at proper place.

Include var_intr.h after definition of hal_intr.h macros but allows overriding
of CYGNUM_HAL_INTERRUPT_RTC.

In Cortex-M architecture, the header hal_intr.h includes var_intr.h twice.
Second one is of course with no effect, but the first one is too early. 
Namely some macros that are defined in hal_intr.h, such as
CYGNUM_HAL_INTERRUPT_EXTERNAL, are used in hal-intr.h. This doesn't seem to
show ill effect so far since usage is by other macros.

Note: The early inclusion of var_intr.h has been introduced by Bug 1001090
Attachment 1092 in order to enable overriding of CYGNUM_HAL_INTERRUPT_RTC by
variant/platform.

The proposed patch includes var_intr.h after definition of hal_intr.h macros
but also allows overriding of CYGNUM_HAL_INTERRUPT_RTC.
