* Improve handling of import statements in GHCi (#20473)Morrow2021-11-171-1/+1
| | | | | | | | | | | | | | | | Currently in GHCi, when given a line of user input we: 1. Attempt to parse and handle it as a statement 2. Otherwise, attempt to parse and handle a single import 3. Otherwise, check if there are imports present (and if so display an error message) 4. Otherwise, attempt to parse a module and only handle the declarations This patch simplifies the process to: Attempt to parse and handle it as a statement Otherwise, attempt to parse a module and handle the imports and declarations This means that multiple imports in a multiline are now accepted, and a multiline containing both imports and declarations is now accepted (as well as when separated by semicolons).

* Testsuite: use ignore_stderr/stdout instead of ignore_outputThomas Miedema2016-06-299-14/+35
| | | | | | | | | | | | | | | | | The problem with ignore_output is that it hides errors for WAY=ghci. GHCi always returns with exit code 0 (unless it is broken itself). For example: ghci015 must have been failing with compile errors for years, but we didn't notice because all output was ignored. Therefore, replace all uses of ignore_output with either ignore_stderr or ignore_stdout. In some cases I opted for adding the expected output. Update submodule hpc and stm.

* Testsuite: open/close stdin/stdout/stderr explicitlyThomas Miedema2016-06-281-1/+1
| | | | | | | | | | | | | | | | | | This allows run_command's to contain `|`, and `no_stdin` isn't necessary anymore. Unfortunately it doesn't fix T7037 on Windows which I had hoped it would (testsuite driver tries to read a file that it just created itself, but the OS says it doesn't exist). The only drawback of this commit is that the command that the testsuite prints to the terminal (for debugging purposes) doesn't mention the files that stdout and stderr are redirected to anymore. This is probably ok. Update submodule unix. Differential Revision: https://phabricator.haskell.org/D1234

* Make 'error' include the CCS call stack when profiledSimon Marlow2015-11-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The idea here is that this gives a more detailed stack trace in two cases: 1. With `-prof` and `-fprof-auto` 2. In GHCi (see #11047) Example, with an error inserted in nofib/shootout/binary-trees: ``` $ ./Main 3 Main: z CallStack (from ImplicitParams): error, called at Main.hs:67:29 in main:Main CallStack (from -prof): Main.check' (Main.hs:(67,1)-(68,82)) Main.check (Main.hs:63:1-21) Main.stretch (Main.hs:32:35-57) Main.main.c (Main.hs:32:9-57) Main.main (Main.hs:(27,1)-(43,42)) Main.CAF (<entire-module>) ``` This doesn't quite obsolete +RTS -xc, which also attempts to display more information in the case when the error is in a CAF, but I'm exploring other solutions to that. Includes submodule updates.

* Make GHCi & TH work when the compiler is built with -profSimon Marlow2015-11-072-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Amazingly, there were zero changes to the byte code generator and very few changes to the interpreter - mainly because we've used good abstractions that hide the differences between profiling and non-profiling. So that bit was pleasantly straightforward, but there were a pile of other wibbles to get the whole test suite through. Note that a compiler built with -prof is now like one built with -dynamic, in that to use TH you have to build the code the same way. For dynamic, we automatically enable -dynamic-too when TH is required, but we don't have anything equivalent for profiling, so you have to explicitly use -prof when building code that uses TH with a profiled compiler. For this reason Cabal won't work with TH. We don't expect to ship a profiled compiler, so I think that's OK.

* base: use Show for ErrorCall in uncaughtExceptionHandlerEric Seidel2015-09-211-0/+2
| | | | | | | | | | | | | The default top-level exception handler now uses the `Show` instance for `ErrorCall` when printing exceptions, so it will actually print the out-of-band data (e.g. `CallStack`s) in compiled binaries, instead of just printing the error message. This also updates the hpc submodule to fix the test output. Reviewed By: austin, thomie Differential Revision: https://phabricator.haskell.org/D1217
