Now that the multitarget testing has settled, clean up the cases where
istarget * is used. This ends up being mostly style unindenting.
|
|
We'll rely on the toolchain probing to determine whether each arch's
tests can be run rather the current configure target. This allows
testing all of the ports in a multitarget configuration.
For now, we don't reformat the files entirely to make it easier to
review, and in case we need to make adjustments. Once this feels
like it's stable, we can flatten the code a bit by removing the if
statement entirely.

The sim_init function was called by runtest for each test when --tool
was set to sim. When we changed to --tool '' to collapse the testsuite
dir, the init function was no longer called on every test. However, it
was still being called explicitly by config/default.exp. It's not clear
why that explicit call ever existed since, in the past, it meant it was
redundant.
Lets drop the single sim_init call in config/default.exp and move it out
to all our tests. This replicates the runtest behavior so we can setup
variables on a per-test basis which allows us to recollapse the sim_path
logic back. We'll also leverage this in the future for toolchain setup.
Also add a few comments clarifying the overall runtime behavior.

Now that all the other toolchain settings have been renamed to match
the dejagnu settings of XXX_FOR_TARGET, rename global_sim_options to
SIMFLAGS_FOR_TARGET too.
|
|
Only a few tests actually use global_ld_options, but we can replace the
sim-specific settings with the dejagnu common LDFLAGS_FOR_TARGET and get
the same result.

Now that ChangeLog entries are no longer used for sim patches,
this commit renames all relevant sim ChangeLog to ChangeLog-2021,
similar to what we would do in the context of the "Start of New
Year" procedure.
The purpose of this change is to avoid people merging ChangeLog
entries by mistake when applying existing commits that they are
currently working on.
Also throw in a .gitignore entry to keep people from adding new
ChangeLog files anywhere in the sim tree.

Since we require ports to use a matching subdir name in the testsuite
tree, we can use that to calculate the $arch value.
|
|
This is needed to move to automake & its dejagnu-provided logic,
and eventually by the unified sim logic. The $arch is used only
to figure out which `run` program to use when running tests, and
as we move to a single top-level build, we can delete this and
use sim/run directly.
|
|
Now that all port tests live under testsuite/sim/*/, and none live
in testsuite/ directly, flatten the structure by moving all of the
dirs under testsuite/sim/ to testsuite/ directly.
We need to stop passing --tool to dejagnu so that it searches all
dirs and not just ones that start with "sim". Since we have no
other dirs in this tree, and no plans to add any, should be fine.
