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.
Stack traces on an unbuffered stderr get out of sync with line-buffered
stdout - usually on Windows terminals or CI logs. This fixes it by
calling C's fflush() on the output buffer in the procedure used for
printing stack traces.
* libbacktrace support
* switch to a generic stack trace overriding mechanism
When "nimStackTraceOverride" is defined, once of the imported modules
can register its own procedure to replace the default stack trace
generation by calling `registerStackTraceOverride(myOwnProc)`.
Tested with `./koch boot -d:release --debugger:native -d:nimStackTraceOverride --import:libbacktrace`
for the compiler itself and `./bin/nim c -r -f --stacktrace:off --debugger:native -d:nimStackTraceOverride --import:libbacktrace foo.nim`
for an external program.
* make the StackTraceOverrideProc {.noinline.}
* first implementation of the =trace and =dispose hooks for the cycle collector
* a cycle collector for ARC: progress
* manual: the .acyclic pragma is a thing once again
* gcbench: adaptations for --gc:arc
* enable valgrind tests for the strutils tests
* testament: better valgrind support
* ARC refactoring: growable jumpstacks
* ARC cycle detector: non-recursive algorithm
* moved and renamed core/ files back to system/
* refactoring: --gc:arc vs --gc:orc since 'orc' is even more experimental and we want to ship --gc:arc soonish
* Fix AVR target to define ints properly
* Fix more than AVR target
* Test to see how robust not using stdint is
* Fix for namespaces using cstdint
* Fix for pre C++11 compilers when using namespaces
* Fix classify to test for subnormality.
* Minor fix.
* Modified to maintain existing API.
* Minor change.
* Removed 32-bit case since float is always 64-bit.
* fix sticky colors in styledWrite
* nimgrep: context printing, colorthemes and other
* add context printing (lines after and before a match)
* nimgrep: add exclude/include options
* nimgrep: improve error printing & symlink handling
* nimgrep: rename dangerous `-r` argument
* add a `--newLine` style option for starting matching/context
lines from a new line
* add color themes: 3 new themes besides default `simple`
* enable printing of multi-line matches with line numbers
* proper display of replace when there was another match replaced at
the same line / context block
* improve cmdline arguments error reporting
* Ref #12103 - adds FreeBSD CI
* Fix getApplFreebsd - length of the string includes the null terminator byte, so minus 1 for result length
* Show last commit in setup task.
* Remove .git from repository URL
* Don't include noisy details showing last commit.
* Add FreeBSD build status badge
* Fix#12182 - disable tconsole on FreeBSD
* Disable tgetaddrinfo on FreebSD as getaddrinfo doesn't support the ICMP protocol.
* Install boehm-gc-threaded
* Use libgc-threaded.so on FreeBSD rather than libgc.so.
* Simplify build failure handling. Update alt text for CI badge.
* Disable test on FreeBSD
* Simplify build config
- use GNU make to build csources
- set PATH variable using the environment key
- remove modification of config to set CC as this is already set
* Install git which seems to be missing from current freebsd images
* Revert change to how path is set
* Add a comment explaining why the length is truncated
* Fix tconsole.
This fixes some tiny issues with using Nim on 16-bit platforms. Not
entirely sure why the AVR chip I was compiling for with "cpu = avr" was
detected as 16-bit, but that's probably another issue..
