Deprecations
|
|
============
|
|
|
|
The following deprecated items are scheduled for future removal:
|
|
|
|
C++11 compiler support
|
|
Verilator currently requires a C++20 or newer compiler for timing, and a
|
|
C++11 or newer compiler for no-timing.
|
|
|
|
Verilator will require C++14 or newer compilers for both compiling
|
|
Verilator and compiling Verilated models with --no-timing no sooner than
|
|
January 2023.
|
|
|
|
Verilator will require C++20 or newer compilers for both compiling
|
|
Verilator and compiling all Verilated models no sooner than January 2025.
|
|
|
|
32-bit compiler support
|
|
Verilator currently regresses both 64-bit and 32-bit pointer modes (GCC's
|
|
`-m64` and `-m32`). Support for 32-bit `-m32` mode will be deprecated no
|
|
sooner than January 2024.
|
|
|
|
Option `-O<letter>`
|
|
The debug `-O<letter>` options have been replaced with
|
|
`-fno-<optimization>` debug options to match GCC. The old options are
|
|
planned for removal no sooner than June 2023.
|
|
|
|
Option `--prof-threads`
|
|
The `--prof-threads` option has been superseded by the `--prof-exec` and
|
|
`--prof-pgo` options and is planned for removal no sooner than April 2023.
|
|
|
|
Verilated model options `+verilator+prof+threads+*`
|
|
The `+verilator+prof+threads+start`, `+verilator+prof+threads+window` and
|
|
`+verilator+prof+threads+file` options have been superseded by the
|
|
`+verilator+prof+exec+start`, `+verilator+prof+exec+window` and
|
|
`+verilator+prof+exec+file` options respectively and are planned for removal
|
|
no sooner than April 2023.
