* Error -> Defect for defects (#13908)Jacek Sieka2020-04-281-1/+1
| | | | | | | | | | | | | | * Error -> Defect for defects The distinction between Error and Defect is subjective, context-dependent and somewhat arbitrary, so when looking at an exception, it's hard to guess what it is - this happens often when looking at a `raises` list _without_ opening the corresponding definition and digging through layers of inheritance. With the help of a little consistency in naming, it's at least possible to start disentangling the two error types and the standard lib can set a good example here.

* fix #13902 distinct uint64 type corruption on 32-bit with borrow (#13907) ↵Timothee Cour2020-04-081-1/+1

* Fix typeSym.getImpl for ref types (#13752)zah2020-03-261-1/+1
| | | | | | | | | | | | | | | | | | | | | * Fix typeSym.getImpl for ref types * Fix a codegen issue affecting the test suite of nim-beacon-chain * Fix tests/stdlib/tjsonmacro To understand the fix better it may help to take a look at the history of the replaced code. The nil check that is removed in this commit was introduced in another fix that failed to identify the root cause of the issue - namely that we allow an object type to exist for which no ast is present: https://github.com/nim-lang/Nim/pull/9601/files The original intention of the code is more obvious here: https://github.com/nim-lang/Nim/pull/9538/files

| | | | | | | | | | | | | | | | | | | | | | | | | 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.
