GPR#268: Hexadecimal notation for floating-point numbers

2015-11-19T09:37:20+00:00

Merge of branch 'hex-float'.

- Add support in byterun/floats.c for conversions between floats and strings in hex notation. We cannot rely on the C standard library here because Microsoft consistently fails at supporting hex notation as standardized in C99. Instead, the conversions are implemented from scratch.
- Add support in the lexer so that hex float literals are recognized in OCaml sources.
- Add support in formats. The ISO C99 format letters for hex floats are %a and %A, but %a is already taken. I chose %h and %H, which are rejected today as bad formats (hence no backward incompatibility) and don't mean anything in C either (h is a modifier, not a format letter).
- Add support in printf. All the trimmings are there in the implementation of %h and %H, including sign modifier and fixed precision.
- Benoit Vaugon contributed support in scanf.

Resolved conflicts:
	boot/ocamlc
	boot/ocamldep
	boot/ocamllex
	parsing/lexer.mll

Code cleanup: replace let-binding of type unit with sequence.

A second attempt to memoize Scanning.from_in_channel using weak pointers.

Scanning.from_channel now uses a weak hash table to record in_channel -> scanbuf associations. This should prevent memory leaks in program that intensively call Scanf.fscanf.

Bug in function check_char corrected: instead of only accepting \r\n as a new

2015-09-13T18:02:03+00:00

line, it accepted any amount of \r followed by \n.
Float scanning code revisited, commenting the code and avoiding side effect
in function application.
Type file_name now used to define in_channel_name, hence its definition goes
before in_channel_name.
open/close_in --> Pervasives.open/close_in when necessary.
Indentation revisited.
