Jakub,
this patch implements firstprivate support for openacc. This is pretty straight
forwards -- they're just regular auto variables, but with an initialization
value from the host.
The gimplify.c implementation is somewhat different to gomp4 branch, as I've
added new bits to enum omp_region_type, rather than add 2 new fields to
omp_region_ctx. The new enums use bits already defined in omp_region_type:
+ ORT_ACC = 0x40, /* An OpenACC region. */
+ ORT_ACC_DATA = ORT_ACC | ORT_TARGET_DATA, /* Data construct. */
+ ORT_ACC_PARALLEL = ORT_ACC | ORT_TARGET, /* Parallel construct */
+ ORT_ACC_KERNELS = ORT_ACC | ORT_TARGET | 0x80, /* Kernels construct. */
On gomp4 we were already setting those bits, but then setting the new fields to
indicate 'openacc'. Many places in gimplify.c where we check for '==
ORT_TARGET_DATA' or ORT_TARGET get changed to '& ORT_TARGET_DATA' etc.
On gomp4 for things like an openacc loop we were setting ORT_WORKSHARE, so
nearly all checks for == ORT_WORKSHARE get an additional '|| X == ORT_ACC'.
Although this patch doesn't make use of the difference between ORT_ACC_KERNELS
and ORT_ACC_PARALLEL, the default handling patch will -- they have different
behaviours.
I think the gimpify.c changes are then obvious from that, but let me know.
in omp-low the changes are to remove 'sorry' and build the initializer exprs in
lower_omp_target.
As you can see this fixes a few xfails.
I'll post the default handling patch, which is much more localized.

gcc/
* gcc/gimplify.c (enum omp_region_type): Add ORT_ACC,
ORT_ACC_DATA, ORT_ACC_PARALLEL, ORT_ACC_KERNELS. Adjust ORT_NONE.
(new_omp_context): Initialize all fields.
(gimple_add_tmp_var): Add ORT_ACC checks.
(gimplify_var_or_parm_decl): Likewise.
(omp_firstprivatize_variable): Likewise. Use ORT_TARGET_DATA as a
mask.
(omp_add_variable): Look in outer contexts for openacc and allow
reductions with other sharing. Add ORT_ACC and ORT_TARGET_DATA
checks.
(omp_notice_variable, omp_is_private, omp_check_private): Add
ORT_ACC checks.
(gimplify_scan_omp_clauses: Treat ORT_ACC as ORT_WORKSHARE.
Permit private openacc reductions.
(gimplify_oacc_cache): Specify ORT_ACC.
(gimplify_omp_workshare): Adjust OpenACC region types.
(gimplify_omp_target_update): Likewise.
* gcc/omp-low.c (scan_sharing_clauses): Remove Openacc
firstprivate sorry.
(lower-rec_input_clauses): Don't handle openacc firstprivate
references here.
(lower_omp_target): Emit initializers for openacc firstprivate vars.
