PR32964 part 1: improve diagnostics of @defined resolution
|
||||
|
||||
The @defined construct is special in that it is attempted to be
|
||||
resolved to literal 1/0 fairly early during semantic analysis pass-2,
|
||||
so that it can guard $context variable references. But this early
|
||||
processing is not that systematic: not all script level constructs
|
||||
properly nest with it. Those cases that don't happen to match end
|
||||
up resolved to 0 as a fallback in late during pass-2, due to PR18079.
|
||||
|
||||
This patch adds verbosity diagnostics for some of these cases, and a
|
||||
warning message for the fallback resolution path. This triggers
|
||||
for the test case associated with this bugzilla report.

PR32964 part 5: tweak type inference propagation
|
||||
|
||||
Because some type inference is now performed earlier than before,
|
||||
coupled with early const-folding (so dead code elimination), tests
|
||||
like semko/binexpr_infer_type.stp started passing with immediately
|
||||
prior code. That's because constructs like (foo*0) got quietly
|
||||
replaced by 0, even if foo was typed pe_string. This patch
|
||||
compensates for this change in behaviour by:
|
||||
|
||||
- typeresolution_info::resolve_2types now propagates types
|
||||
more aggressively & recursively in its three-way inference,
|
||||
so that the unknown x string x long case is detected in one
|
||||
incoming invocation of the function, instead of being
|
||||
deferred to some unknown later relaxation-iteration round.
|
||||
|
||||
- typeresolution_info::mismatch reporting errors, independent
|
||||
of "assert_resolvability". That flag was most likely meant
|
||||
for detection & rejection of pe_unknown types at the end of
|
||||
all the optimization stuff, not for ignoring outright known
|
||||
conflicts.

It turns out there was one old testcase that relied on type

non-checking upon elided variables. This test has been removed, and

the change mentioned in NEWS. Unfortunately, this is is hard to make

RHEL-90805: Fix dev.stp tapset to work with RHEL 9.7 kernel
|
||||
|
||||
RHEL 9.7 kernels have backported block dev support from Linux 6.14.
|
||||
The test in the dev.stp tapset checked the kernel version to determine
|
||||
where to get information and that test did not work in the case of
|
||||
code backported to the older RHEL 9 Linux 5.14 kernel. The dev.stp
|
||||
code has been reworked to search for the particular member field
|
||||
holding the information instead.
