| | | | | | | | | | | | | | | | | | | | | | | | | allocShared0. (#13190) * Cleanup, remove lib/system/allocators.nim. seqs_v2 and strs_v2 now use allocShared0 by default. * Fixed -d:useMalloc allocShared / reallocShared / deallocShared. These now use the alloc/dealloc/realloc implementation that also takes care of zeroing memory at realloc. * Removed debug printfs * Removed unpairedEnvAllocs() from tests/destructor/tnewruntime_misc * More mmdisp cleanups. The shared allocators do not need to zero memory or throw since the regular ones already do that * Introduced realloc0 and reallocShared0, these procs are now used by strs_v2 and seqs_v2. This also allowed the -d:useMalloc allocator to drop the extra header with allocation length. * Moved strs_v2/seqs_v2 'allocated' flag into 'cap' field * Added 'getAllocStats()' to get low level alloc/dealloc counters. Enable with -d:allocStats * *allocShared implementations for boehm and go allocators now depend on the proper *allocImpl procs
* Unexport even more symbols (#13214)alaviss2020-01-231-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * system/gc: don't export markStackAndRegisters * compiler/cgen: unexport internal symbols As these functions are Nim-specific walkaround against C's optimization schemes, they don't serve any purpose being exported. * compiler/cgen: don't export global var unless marked * compiler/ccgthreadvars: don't export threadvar unless marked * tests/dll/visibility: also check for exports This ensure that these changes don't break manual exports. * compiler/cgen: hide all variables created for constants * compiler/ccgtypes: don't export RTTI variables * compiler/ccgexprs: make all complex const static * nimbase.h: fix export for windows * compiler/cgen, ccgthreadvars: export variables correctly For C/C++ variables, `extern` means that the variable is defined in an another unit. Added a new N_LIB_EXPORT_VAR to correctly export variables.

* --exception:goto switch for deterministic exception handling (#12977)Andreas Rumpf2020-01-011-2/+5
| | | | | This implements "deterministic" exception handling for Nim based on goto instead of setjmp. This means raising an exception is much cheaper than in C++'s table based implementations. Supports hard realtime systems. Default for --gc:arc and the C target because it's generally a good idea and arc is all about deterministic behavior. Note: This implies that fatal runtime traps are not catchable anymore! This needs to be documented.
