Patch 2/3 of the transition step 1 described in
https://discourse.llvm.org/t/rfc-enabling-the-hlfir-lowering-by-default/72778/7.
All the modified tests are still here since coverage for the direct
lowering to FIR was still needed while it was default. Some already have
an HLFIR version, some have not and will need to be ported in step 2
described in the RFC.
Note that another 147 lit tests use -emit-fir/-emit-llvm outputs but do
not need a flag since the HLFIR/no HLFIR output is the same for what is
being tested.
Change the separator in the `uniqueCGIdent` method to `X`. This change
is required to enable OpenMP offloading for the NVPTX target, as dots
are not valid identifiers in PTX and `uniqueCGIdent` is used to mangle
some literals. Follow up patches will change the remainder of `.`
appearances in names to `X` and add support for the NVPTX target.
Following RFC at
https://discourse.llvm.org/t/rfc-ffp-contract-default-value/66301
This adds the `fastmath<contract>` attribute to `fir.call` and some
floating point arithmetic operations (hence the many test changes).
Instead of testing for this specific attribute, I am using a regular
expression to match any attributes.
Flang is manually mangling names for memset/memcpy/memmove
intrinsics, so we need to update the mangling to use the opaque
pointer format (p0 instead of p0i8).
This patch adds test for calls with POINTER dummy arguments on the caller side.
It also fixes some formatting error that was introduced when upstreaming
the other pointer tests.
This patch is part of the upstreaming effort from fir-dev branch.
