commit 2a17fc858bebf19ee61eec608ebcb76c9c858529
Author: Marek Marecki <address@hidden>
Date:   Wed Sep 12 20:31:36 2018 +0200

    Static analyser has basic understanding of the `integer` instruction

commit 8153e4a7ad8c9cadc3311b98f22ba32466ad7174
Author: Marek Marecki <address@hidden>
Date:   Wed Sep 12 20:27:45 2018 +0200

    Prepare class representing types of values for use in static analyser
    
    Simple bitmask is not sufficient for representing nested or complex
    types, so a full-blown structs will be used instead. This will provide
    additional flexibility (e.g. embedding actual, or estimated, values
    contained in registers analysed to use them in analysis).

commit 98a4e45ee627ea7e2a20aba995c3c33cb6a6fe56
Author: Marek Marecki <address@hidden>
Date:   Wed Sep 12 20:27:04 2018 +0200

    Fix: add tokens to fragments

commit 734cbbb14894c7b161a7e932dcd115656b0b1b8a
Author: Marek Marecki <address@hidden>
Date:   Wed Sep 12 20:26:32 2018 +0200

    Fix: allow accessing tokens of an operand

commit 05be0a5461f2b0884b83c653d9c497d01233b7cf
Author: Marek Marecki <address@hidden>
Date:   Mon Sep 10 20:00:39 2018 +0200

    Detect reusing a name for a different register

commit d4221c58422b397902b8746187cc4e10bec384a7
Author: Marek Marecki <address@hidden>
Date:   Mon Sep 10 19:52:49 2018 +0200

    Detect renaming already named registers

commit 89b01bf3c9e655f539f3f4f3fe495c221c87de9b
Author: Marek Marecki <address@hidden>
Date:   Mon Sep 10 19:43:23 2018 +0200

    Handle iota and register naming
    
    This commit makes the new static analyser recognise the `iota` keyword
    and `.name:` directives. Not all errors are handled yet, e.g. renaming
    already named registers, or reusing a name for another register index
    are not yet detected.

commit 7278829092235f805e70e349307c5e5c51119be8
Author: Marek Marecki <address@hidden>
Date:   Mon Sep 10 19:42:29 2018 +0200

    Prepare function state to handle iotas and register names

commit b749505cfb990bb869a6185c88c652d483e83946
Author: Marek Marecki <address@hidden>
Date:   Mon Sep 10 19:41:58 2018 +0200

    Add an error for out-of-range register indexes

commit 1849ccbe6d846648739098c7e1a0b2c723c16158
Author: Marek Marecki <address@hidden>
Date:   Mon Sep 10 19:30:46 2018 +0200

    Initialise function state with the information about local registers 
allocated

commit 5b03269a245171bb608db979ea90bb8af68faedd
Author: Marek Marecki <address@hidden>
Date:   Mon Sep 10 19:26:39 2018 +0200

    Create function state to store information about the function's state
    
    At every line (either a directive, or an instruction) the state is
    mutated and the static analyser decides whether the state is valid, or
    in error.

commit b539fd8fb548742d240c5b041031ca5580e23b03
Author: Marek Marecki <address@hidden>
Date:   Mon Sep 10 19:21:49 2018 +0200

    Fix: line numbers are properly aligned in error listings
    
    Making classic off-by-one error, I forgot that line indexes are
    zero-based but when displayed to humans should be converted to
    one-based.

commit 9ef8c18dea5c7b263742cb7152dad98c6be17c05
Author: Marek Marecki <address@hidden>
Date:   Mon Sep 10 19:21:26 2018 +0200

    Add error for out-of-range register addresses created by iota
