* fixes #13881Andreas Rumpf2020-05-121-3/+4
| | | | | | * fixes #13881 * documented changed requirements for system.onThreadDestruction * destructors.rst: update the documentation
* 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.
* forward type alignment information to seqs (#12430)Arne Döring2020-04-191-7/+8
|
* catchable defects (#13626)Andreas Rumpf2020-03-121-2/+6
| | | | | | | | | | * allow defects to be caught even for --exceptions:goto (WIP) * implemented the new --panics:on|off switch; refs https://github.com/nim-lang/RFCs/issues/180 * new implementation for integer overflow checking * produce a warning if a user-defined exception type inherits from Exception directly * applied Timothee's suggestions; improved the documentation and replace the term 'checked runtime check' by 'panic' * fixes #13627 * don't inherit from Exception directly
* Unexport even more symbols (#13214)alaviss2020-01-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
