whitequark 7191dd16f9 Use C++11 final/override keywords. 2020-06-18 23:34:52 +00:00
Rupert Swarbrick d681c9df85 Pass some more args by reference in select.cc 
Before this patch, the code passed around std::string objects by
value. It's probably not a hot-spot, but it can't hurt to avoid the
copying.

Removing the copy and clean-up code means the resulting code is ~6.1kb
smaller when compiled with GCC 9.3 and standard settings.

Rupert Swarbrick 061d1f0c07 Minor optimisations in select.cc's match_ids function 
- Pass a string argument by reference

  - Avoid multiple calls to IdString::str and IdString::c_str

  - Avoid combining checks for size > 0 and first char (C strings are
    null terminated, so foo[0] != '\0' implies that foo has positive
    length)

Rupert Swarbrick 0d9beb5b2e Silence warning in select.cc 
With GCC 9.3, at least, compiling select.cc spits out a warning about
an implausible bound being passed to strncmp. This comes from inlining
IdString::compare(): it turns out that passing std::string::npos as a
bound to strncmp triggers it.

This patch replaces the compare call with a memcmp with the same
effect. The repeated calls to IdString::c_str are slightly
inefficient, but I'll address that in a follow-up commit.

whitequark efa278e232 Fix typographical and grammatical errors and inconsistencies. 
The initial list of hits was generated with the codespell command
below, and each hit was evaluated and fixed manually while taking
context into consideration.

    DIRS="kernel/ frontends/ backends/ passes/ techlibs/"
    DIRS="${DIRS} libs/ezsat/ libs/subcircuit"
    codespell $DIRS -S *.o -L upto,iff,thru,synopsys,uint

More hits were found by looking through comments and strings manually.

whitequark f6412d7109 select: print selection if a -assert-* flag causes an error. 2018-12-16 15:44:29 +00:00
Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)

eshellko 9a742f4069 Added 'assert-limit' option for 'select' command 
For resource limited designs such as FPGA it can be useful to specify limit of specific resources available on board. So user can check if he should change RTL as early as mapping done.
