Bug ID: 52097
Summary: No dump output for programs with semantic errors
Product: flang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Driver
Assignee: unassignedb...@nondot.org
Reporter: psteinf...@nvidia.com
CC: andrzej.warzyn...@gmail.com, david.tr...@arm.com,

If I invoke the front end on a program with a semantic error and ask it to dump
the symbol table or the parse tree, no dump output appears.
Here's an example program with a semantic error:
program bad
real,pointer :: x
x = null() ! Error - must be pointer assignment
end
If this program is in the file "bad.f90", and I invoke the compiler as follows:
flang-new -fc1 -fdebug-dump-all -I include/flang
I don't get any dump output. Rather I only get the following messages:
error: Semantic errors in bad.f90
./bad.f90:3:3: error: A NULL() pointer is not allowed in a non-pointer
intrinsic assignment statement
x = null() ! Error - must be pointer assignment
^^^^^^^^^^
Also, no messages appear that indicate that dumping was skipped.
