ahhh. lovely. ok, so I'll hold off checking in the approved front end patch until I rerun the tool. I can pre-define a set of macros in the tool to mimic these command-line options that might be seen in order to make sure that headers arent removed that cause these kinds of issues.Hi! "Hooray for the C programming language's module system"... ;-) On Fri, 23 Oct 2015 12:53:40 -0400, Andrew MacLeod <amacleod@redhat.com> wrote:Just finished running... I think the external hard drive was slowing down this run :-P It took quite a while. Anyway, this is the reduction patch independent of the header-ordering patch... ie, that patch needs to be applied before this one. So this should be mostly just removals. I also need to follow up and build all the target and bootstrap from scratch to make sure there arent any weirdnesses with it. But you can at least get a look at it now.Similar to the ENABLE_OFFLOADING preprocessor conditional as reported by Cesar and Nathan, I've run into a problem with code "hidden" behind ENABLE_FOLD_CHECKING, and this has independently also been reported as <https://gcc.gnu.org/PR68166>: [...]/source-gcc/gcc/fold-const.c: In function 'tree_node* fold(tree)': [...]/source-gcc/gcc/fold-const.c:12038:18: error: aggregate 'md5_ctx ctx' has incomplete type and cannot be defined struct md5_ctx ctx;
After it runs, I'll see if there were any front end files that need adjusting to account for this, then I'll check them in.
I will also rerun the tool over the next week or so on all the backend.a files from the revision just before I merged to see if anything else comes out of the woodwork. There could still be a hidden case or two like this.
A quick grep shows the following macros should probably be predefined: ENABLE_ASSERT_CHECKING ENABLE_CHECKING ENABLE_DECIMAL_BID_FORMAT ENABLE_DECIMAL_FLOAT ENABLE_DEFAULT_PIE ENABLE_DEFAULT_SSP ENABLE_DF_CHECKING ENABLE_FIXED_POINT ENABLE_FOLD_CHECKING ENABLE_GC_ALWAYS_COLLECT ENABLE_GC_CHECKING ENABLE_GIMPLE_CHECKING ENABLE_IRA_CHECKING ENABLE_LD_BUILDID ENABLE_LIBQUADMATH_SUPPORT ENABLE_LTO ENABLE_NLS ENABLE_OFFLOADING ENABLE_PLUGIN ENABLE_PLUGINS ENABLE_PTHREADS ENABLE_RTL_CHECKING ENABLE_RTL_FLAG_CHECKING ENABLE_RUNTIME_CHECKING ENABLE_SHARED_LIBGCC ENABLE_TREE_CHECKING ENABLE_TYPES_CHECKING ENABLE_VALGRIND_ANNOTATIONS ENABLE_VALGRIND_CHECKING ENABLE_WIN32_REGISTRYAnyone think of anything else the might come from a command line that wouldnt be seen otherwise?
