library/lexer.m:
Merge the 'integer' and 'big_integer' tokens and extend them to include
signedness and size information. This conforms to recent changes to
the rest of the system and is another step towards supporting additional
types of integer literal.
library/parser.m:
mdbcomp/trace_counts.m:
Conform to the above change.
tests/hard_coded/impl_def_lex.exp:
tests/hard_coded/impl_def_lex_string.exp:
tests/hard_coded/lexer_bigint.exp:
tests/hard_coded/lexer_zero.exp*:
tests/hard_coded/parse_number_from_string.exp*:
Update these expected outputs.
The lexer was not allowing underscores between leading zeros in decimal integer
literals and float literals (e.g. 0_0 or 0_0.0).
library/lexer.m:
Allow underscores in the above cases.
tests/hard_coded/parse_number_from_io.{m,exp,exp2,exp3}:
tests/hard_coded/parse_number_from_string.{m,exp,exp2,exp3}:
Extend these tests to cover the above cases.
tests/invalid/invalid_binary_literal.err_exp:
tests/invalid/invalid_octal_literal.err_exp:
tests/invalid/invalid_hex_literal.err_exp:
Conform to the above change.
Standardize terminology in error messages about ill-formed numeric literals.
doc/reference_manual.texi:
Document underscores in numeric literals.
Add a TODO comment about a future piece of work.
NEWS:
Announce the addition of support for underscores in numeric literals.
library/lexer.m:
Use the term "literal" instead of "constant" or "token" when
referring to numeric literals in error messages.
s/hex/hexadecimal/ in those same error messages.
tests/hard_coded/parse_number_from_string.exp*:
tests/invalid/invalid_{binary,decimal,hex,octal}_literal.err_exp:
Conform to the above change in error messages from the lexer.
library/lexer.m:
Add a missing predicate.
tests/hard_coded/parse_number_from_io.exp[23]:
tests/hard_coded/parse_number_from_string.exp[23]:
Additional expected outputs for the Java and C# backends.
