Dear Users,

1. A new branch "k64-1-6" has been created to install a new allocation of objects. It will be more 64-bit savvy and more efficient in the space and time. It needs more debug, especially for EPICS-related things which are not easily debugged. A rough description is in src/inc/k64.readme:

- Any obeject specifier is embedded in the NaN space of IEEE real*8 format:

(integer8) kobj = (integer8) ktype + (integer8) kaddr;

where ktype is the type of object, with bit patterns defined in TFCODE.inc:

integer*8 ktfoper,ktflist,ktfstring,ktfsymbol,ktfpat,ktfobj,
$ ktfmask,ktamask,ktrmask,ktfnull,ktfnr,ktfref,ktfother,
$ ktomask
parameter (
$ ktfnull =int8(z'0000000000000000'),
$ ktfother =int8(z'0006000000000000'),
$ ktfnr =int8(z'0008000000000000'),
$ ktfoper =int8(z'0008000000000000'),
$ ktfref =int8(z'000e000000000000'),
$ ktfobj =int8(z'8008000000000000'),
$ ktflist =int8(z'8008000000000000'),
$ ktfpat =int8(z'800a000000000000'),
$ ktfstring=int8(z'800c000000000000'),
$ ktfsymbol=int8(z'800e000000000000'),
$ ktfmask =int8(z'fffe000000000000'),
$ ktomask =int8(z'fff8000000000000'),
$ ktrmask =int8(z'7ff8000000000000'),
$ ktamask =int8(z'0001ffffffffffff'))

- kaddr is the address ,ie. the object is stored at klist(kaddr). If ktype is an
operator (ktfoper), kaddr means the code of operator.

- A real*8 number x has a pattern iand(ktrmask, x) .ne. ktfnr .

- A list a is stored at klist(ka = ktfaddr(k)) as:

ilist(2,ka-1): Length[a], 32 bit.
klist(ka) : head, a[[0]]
klist(ka+1) : a[[1]]
klist(ka+2) : a[[2]]
....

- Sad's stack is allocated in a space ktastk, within 32 bit index.

- Lengths of list and string is less than 2**31.

- There are a few functions defined in TFSF.inc to handle the patterns.

Dear Users,

1. The bit patterns of the types are corrected to map to NaN. The pervious ones were mapping to subnormals, not NaN.

Dear Users,

1. Changes are summarized in src/inc/changelog.

The compiler options in sad.conf in my case are as following:

SYS_FC_ABIOPT= -Wall -m64
_USE_GFORTRAN= YES
_USE_G95= NO
COMPILER=GNU
SYS_CC_ABIOPT= -Wall -std=gnu11 -m64
_SYS_COPT_GCC= -Wall -std=gnu11
CC=gcc-mp-4.7
FC=gfortran-mp-4.7

FOPT= -g -O3 -fno-second-underscore -fdollar-ok -fargument-alias -frecursive -fbackslash -std=legacy -fall-intrinsics -mtune=native -march=native -Wall -m64 -fno-range-check -fbacktrace -falign-functions=64 -falign-jumps -falign-loops -falign-labels
COPT= -g -O3 -Wall -std=gnu11 -m64

My minimum sad.conf on FreeBSD/amd64(afsad*)

USE_GCC=4.8.0
FOPT+=-fno-range-check

My minimum sad.conf on OS X 10.8 (Mountain Lion)

USE_GCC=4.8.0
FOPT+=-fno-range-check -frecursive
COPT+=-Wno-variadic-macros

Dear Users,

1. The next version 1.0.10.6.1k64 will support the "KG sequence" such as "`fb`n`dx" using translation to Unicodes in the case of Xft.Some recent annoying behavior in Canvas, etc. will be solved, hopefully. As this change was made for the k64-1-6 branch, merging into the main branch may take for a while.

Dear Users,

As debugging of k64 has been done including EPICS, it will be merged to the main branch, probably in the next week. Of course nothing can be perfect anyway but it may be more efficient to debug involving more users....

Recent changes are listed below (src/inc/changelog):

7/19/2012
