defca6e34d Started simplifying some of the C backend in light of the new changes, and made a few fixes 
The first few cgtests (at least) now pass with the new system in the C backend.

87fefcb66d Fiddled with the new variable stuff in the C backend, and now variable subscripts seem to work 2009-03-21 19:30:29 +00:00

ca207f7291 Quickly implemented the first version of a revamp of the genVariable code in the C backend 
Surprisingly, the generated code seems to be compiled by GCC without warnings.  Array subscripts are currently unimplemented (a star, i.e. equivalent of subscript 0) is used wherever there should be a subscript.

The new mechanism is based on working out the C type of the original variable/abbrev-mode, the C type of the desired variable/abbrev-mode, and works out how many *s or &s to insert to coerce it to the right type.

1343954c2f Added an option to automatically run indent on C/C++ source before running GCC 
This option is very handy when debugging the C/C++ output of Tock when GCC gives a compiler error.

77be0c1137 Add some testcases for usage-checking on user-defined array types. 
These were based on KRoC bug #194, submitted by Jonathan May.

a1585c74a9 Fixed inferTypes so that it again handles Specifications in Structured ExpressionList in function definitions 2009-02-11 11:53:04 +00:00
Neil Brown
152f5fc252 Changed the abbreviation checking so that it doesn't check nonce names 
When we pull up names (which happens before abbreviation checking), we create a lot of nonces with greater scope than the original variables.  When we go to abbreviation check this, we therefore set off lots of false alarms about originally safe code.  So to fix this, the easiest method seems to be turning off checking on all the names introduced by the compiler.
