JALv2 Homepage

Welcome to the JALv2 homepage. JALv2 is a rewrite of Wouter van Ooijen's famous Just Another Language.

Release history:

2.4m -- 26 Dec 2009

Fixed documentation for '-include'
Added '[no-]asm', '[no-]codfile', '[no-]log', '[no-]lst' '[no-]hex'.
IF expr THEN END IF caused the compiler to crash
Software stack was not being calculated when -no-variable-reuse in effect.
Directly accessing the 0th element (ch = buf[0]) of a pointer caused either an assertion failure or a segfault
Fixed COD generation
Added ID programming support with PRAGMA ID and PRAGMA IDDATA
Added 'movlb 0' to the ISR preamble on 16 bit cores
Fixed `db' & `dw' on 16 bit cores
Fixed PC which was formerly 16 bits, but can be 32 bits on the 16 bit cores.
Restructed the archive directory layout
Converted the three major guides (jalv2, jalv2opt, jalv2pragma) to docbook format in the hopes that this will help me keep everything up to date.
EEPROM data on the 16 bit cores started at location 0 ('cause the variable created was only 16 bits, whereas eeprom on the 16 bit cores starts higher than 0xffff).
a re-entrant function taking an array parameter caused an invalid assertion failure
in some cases a SEGFAULT would occur when passing an array parameter
turned on const comparison warnings (when a comparison is always TRUE or FALSE)
turned on overflow warnings (when a universal value is used that does not fit with its counterpart)
fixed COD file generation
check function parameters for type & overflow
comparing a single bit variable and a single bit constant does not work if -no-expr_reduce is set.
emit an error if an attempt is made to create a bit array (bit arrays are not supported).
added `pragma bootloader bloader' and `pragma bootloader loader18'
fixed `pramga' --> `pragma' in the inline error message
fixed the TRIS parameters in the online manual
added `addwfc' to inline assembly
fixed aliasing at different block levels (eg, an alias in a procedure referencing a global)

2.4l -- 7 Aug 2009

-const-detect ordered the constant big endian instead if little endian
16 bit code generation fixed to match mpasm (namely, the PC is shown in bytes not words)
Added inline assembly: reset
A procedure taking a volatile parameter and also re-entrant would cause an assert()
Changed re-rentrant entry/exit to not use stkpush/pop
A re-entrant function's return value was over-written if there were any non-volatile OUT paramters

added a numeric option to -loader18 to set the offset Examples:

-loader18      : starts the code at 2048
-loader18 4096 : starts the code at 4096

Added units to jalpragm.txt to explain that for `PRAGMA CODE size', size is in WORDs for 12/14 bit cores, and BYTEs for 16 bit cores (thanks MicroChip!). This follows from the second bullet above.
Included inclue assembly opcodes: rlcf/rlncf/rrcf/rrncf
Fixed 16-bit code to use rrcf instead of rrf
Make sure variables don't span banks even if the banks are contiguous (a problem seen on 16 bit cores).
`ALIAS...IS' should work even if the underlying variable is only a pseudo-variable
Output of `Code area' was screwy on 16 bit cores
Changed `pragma code' on the 18 series to use bytes instead of words
