[Tinyos-devel] nesC 1.2.5 available

[David Gay]

>From sourceforge, as usual. There should be an rpm coming to
www.tinyos.net soon (Kristin, can you do this?)

Changes in nesC 1.2.5
=====================
- nescc-mig now generates C (ncg has supported C since 1.1.2)
- add __builtin_offsetof keyword to make recent gcc's happy,
  and update the gcc-specific asm syntax to reflect recent
  gcc changes
- allow types defined in interface files to be used immediately in generic
  interface arguments (e.g., interface Timer<TMilli>, where TMilli is
  defined in Timer.nc)
- updates to automatic inlining - code should be slightly smaller
- @spontaneous() attribute is automatically added to the __nesc_XXX
  functions used by the compiler
- atomic optimisation (experimental): if you specify -fnesc-optimize-atomic,
  two optimisations are performed:
  o outermost atomics call __nesc_disable/enable_interrupt, which can assume
    that interrupts are initially enabled
  o "simple" atomic statements have no overhead (interrupts are not disabled)
    simple atomic statements are those:
    - with no accesses to shared state
    - or, at most one access to one byte of shared state
- bug fixes
