Improvements:

. Add schematic of EM6819 REva daughterboard version 2.0 in docs
. Add information about GCC4 in Getting Started doc:
    . Versions and official status
    . Spill mechanism
    . Empty sections limitation
. Add environment variables C816_GCC3_PATH and C816_GCC4_PATH.
    for scripts that need to select the version of the compiler.

Fixes:

. Various GCC4 compiler engineering fixes:
    . Give priority to indirect attribute over command-line option -mpage0-mvs
   . Make sure all zero-initialized variables go in bss (or page0_bss),
      not in data (nor page0_data) section
   . Prevent presence or absence of static keyword to affect the data/bss placement
   . Use software calls by default.
      For compatibility with old command-line project designed with GCC3.
   . Fix some compiler crashes.
. Watches: Corrected stacked variable display.

Improvements:

. GCC4 is now the default default toolchain.
 GCC3 is still available (only for Windows 8 or older versions).
. Document new GASP ADP.
. Added sub-sections management in all linker script files (for GCC4).
. Stacked variables: Display RAM address rather than just offset from
 frame/stack pointer.
. Detect and report empty linker script file name.
. Install isn't possible anymore if the GNU directory is present to
 avoid GCC3/GCC4 mix.

Fixes:

. Remove persistent error messages after programming but not debugging.
. Cleanup "bad breakpoint" issues management.
. Remove GCC4 warning about "fast_cwd" in Windows 10.
. Hide peripheral bits that are not in EM6819xx-B300 devices.
. GCC4 properly supports 'section' attribute: Non page0 section
 variables are now correctly indirectly accessed.
. GCC4: Added attribute page0 as an alias to page_0 and attribute data
 as an alias to indirect.
. GCC4: Compiler didn't generate accurate debug information (Dwarf) for
 stacked variables.
. GCC4: Added missing segment information for some variables.

Improvements: . Support of enumerated type elements in debug watches. . Debugger supports also Dwarf 4 format. Changes: . EM6869 device removed from RKit-C816. EM6869 support is now provided through add-on distributed by Electronic Marin. Contact Electronic Marin for more information and for getting the add-on files. Fixes: . SX8810 debug: correct management of sleep modes. . SX8810_pgm: (programming): correct verification: ignore breakpoint and protection bits. . SX8810_pgm: (programming): correct dump and verification: last byte as always read as 0. . Fixup in "move dest, #LOWORD(src)" wasn't properly handled by LD.

December 7th, 2012: Status change: . GCC4 is validated. The version that is present in RKit-C816 1.10.12.0215 has successfully passed all tests. Please note, that documentation in the software still indicates that this version is "in test". Consider this "in test" statement as obsolete. Fixes: . GCC4: correct page0 static variables . GCC4: correct float/double constants encoding
