This removes code related to HP9000, HPTIMERBUG, and HPUX defines. It leaves KB_HP9000 for now as I'm not sure about renumbering those constants. This should not impact any of the core emulation code.

Flag Name Meaning/Usage
|
|
_________ ________________________________________________________
|
|
BYTESWAP Used when compiling for a hardware architecture that has
|
|
byte-swapped words and word-swapped 32-bit cells, e.g. 80386.
|
|
SYSVSIGNALS True when compiling on a system that requires the use of
|
|
SYSV (rather than BSD) signal-handling code (just MIPS & ISC
|
|
for 486, now).
|
|
SYSVONLY True when compiling on a system that has little or no
|
|
BSD support (the ISC unix for 486, or MIPS). E.g. gettimofday
|
|
is missing.
|
|
I386 True if compiling for the Sun386i (not just any 80386);
|
|
used because the 386i's display controller is odd.
|
|
OS4 True if compiling for SunOS 4.x
|
|
|
|
NOPIXRECT Used to suppress pixrect/pixwin options when they're not
|
|
needed or not available. True if XWINDOW is.
|
|
|
|
AIX True if compiling for AIX
|
|
AIXPS2 True if compiling for PS/2 under AIX (our flag)
|
|
sparc True if we're compiling on a SPARC machine.
|
|
mc68020 True if we're compiling on a Motorola 680x0 machine.
|
|
sun3 We're compiling for a Sun-3.
|
|
RS6000 We're compiling for the RS/6000 processor.
|
|
DEC3100 We're compiling for the DECStation 3100.
|
|
RISCOS We're compiling for the MIPS RISCstation under RISCOS.
|
|
|
|
UNSAFE If true, enables the "fast" version of 68020 opcodes.
|
|
NOASM If true, suppress any attempt to include assembler
|
|
versions of things in the emulator. In 'lispemul.c',
|
|
if this is true, disables:
|
|
SUN3_OS3_IL
|
|
SUN3_OS4_IL
|
|
SUN4_OS4_IL
|
|
OPDISP
|
|
NATIVETRAN
|
|
UNSAFE
|
|
PROFILE
|
|
and enables NOASMFNCALL
|
|
C_ONLY
|
|
SUN4_OS4_IL Try assembler peephole optimizations for SPARC & SunOS4.x
|
|
SUN3_OS3_IL Try assembler peephole optimizations for 68K & SunOS 3.x
|
|
SUN3_OS4_IL Try assembler peephole optimizations for 68K & SunOS 4.x
|
|
SUN3_OS3_OR_OS4_IL Try asm optimizations for 68K & either sunOS. This is
|
|
turned on whenever either of SUN3_OS3_IL or SUN3_OS4_IL is on.
|
|
|
|
OPDISP Use "fast-opcode-dispatch" macros
|
|
SPARCDISP Use fast-opcode-dispatch macros on SPARC
|
|
|
|
|
|
|
|
|
|
--Debugging/Tracing/Check-enabling flags--
|
|
|
|
DEBUG Used when debugging, to enclose trace and dump code.
|
|
Best usage is with DBPRINT((controlString, args*));, which
|
|
calls printf, and compiles only if DEBUG is true. See
|
|
dbprint.h for the definition.
|
|
TRACE
|
|
TRACE2
|
|
TRASE
|
|
OPTRACE If true, the dispatch loop prints the PC & opcode each time thru
|
|
FNTRACE If true, you see the name of each function called.
|
|
STACKCHECK If true, you see unusual cases of stack manipulation
|
|
traced. E.g., the hard cases of RETURN, like non-contiguous
|
|
stack frames, get mentioned.
|
|
LISPTRACE True if you want to see LISP calls & returns traced to
|
|
stdout; Generally, for traces of lisp-level events.
|
|
PROFILE If true, the profiling control code is enabled. You must
|
|
also change the optflags to contain -p or -pg, to use prof
|
|
or gprof, respectively.
|
|
CHECK
|
|
FSBCHECK If true, you see a trace of large free stack blocks when
|
|
the stack is manipulated; was used for debugging stack code.
|
|
FSMESSAGE If true, prints a message telling you about the hard links
|
|
it makes (in support of version numbering), as it makes them.
|
|
|
|
WINDOW
|
|
INIT Used when compiling an emulator to build a loadup. Use it
|
|
to dike out code that deals with network initialization, e.g.
|
|
|
|
MYOPTRACE Used to check the stack's validity on each opcode execution.
|
|
Requires NOASM, and the absence of SUN..._IL and SPARCDISP &c.
|
|
|
|
PCTRACE When true, compiles in a 100-long ring buffer that holds the
|
|
last 100 PCs, Function-blocks, and Opcodes executed. "pccounter"
|
|
is the offset where the next one will go. Also requires NOASM.
|
|
The 3 tables are called pc_table, fn_table, and op_table.
|
|
|
|
|
|
|
|
|
|
--Flags that control new features, features under test, etc.--
|
|
|
|
DISPLAYBUFFER 10/3/89 JDS -- enables the experimental code for copying
|
|
changed portions of the display bank to the frame buffer.
|
|
Meant for supporting mono mode on a CG6 with no single-bit
|
|
bitplane. 1/22/91 JDS: This is now the standard flag for
|
|
compiling for color displays.
|
|
FSERROR Enables the emulator's returning Unix error codes for
|
|
{DSK} & {UNIX} operations, so Lisp can decode them and
|
|
give better indication of problems. FEATURE STANDARD IN 1.1
|
|
WINDOW
|
|
FLIPCURSOR If true, the "sandbar" line in the cursor will get flipped
|
|
by the C stack-frame-moving code, just as it does on a D
|
|
machine. Otherwise, you don't see it.
|
|
ORG_FILPCORSORBAR If true, you get the pixwin version of cursor changing;
|
|
otherwise, it gets done by direct writes into the display
|
|
region.
|
|
OLD_CURSOR If true, uses the pixwin cursor code (e.g., win_setcursor);
|
|
otherwise, uses the direct-write technique.
|
|
NATIVETRAN If true, code to support the native-code translator is
|
|
included in the emulator. This feature was never released,
|
|
and most such code is probably obsolete.
|
|
OS4_TYPE4BUG If true, includes the patches around SunOS 4.0.x's failure
|
|
to tell you you've got a Type-4 keyboard.
|
|
ALLDIRSEARCH CURRENTLY HARD DISABLED IN directory.c; looks like it
|
|
controlled recursive directory searches??
|
|
KBINT If true (it looks like??), the emulator does most of the KBD
|
|
transition processing in C, rather than interrupting LISP for
|
|
it, and the transition interrupts happen when the OS signals
|
|
a transition, rather than by polling?
|
|
RS232INT If true, the RS232 device (NOT USED, a translation of Lisp's
|
|
code), uses the interrupt signalling support of timer.c to
|
|
know when to read characters. NOT USED, probably obsolete.
|
|
TTYINT Analogous to RS232INT, for the translated TTY device.
|
|
ETHERINT
|
|
COLOR If TRUE, supports 8bits-per-pixel color on CG4 and CG6 frame
|
|
buffer of Sun work station. IF COLOR is TRUE, don't use OLD_CURSOR
|
|
flag.
|
|
CATCH If true, includes some CATCH C code, for finding the blip,
|
|
finding variable names and PVAR names in frames. As of 10/2/89
|
|
this code is unused, and is called nowhere else in the system.
|
|
RECLAIMINC If true, then the RECLAIMCELL opcode calls gcreclaimcell in
|
|
C; otherwise it punts. As of 10/3/89, this was never debugged
|
|
and is not in any system. Probably fairly easy to debug??
|
|
KB_SUN4 The kbd type for the Type-4 keyboard. Defined only because
|
|
older OS versions of the compiler don't define it automatically.
|
|
FUJI If true, and you don't set the LDEKBDTYPE environment variable,
|
|
you'll get a nasty message asking you to set it before
|
|
running lisp. Otherwise, you'll default to a type-3 kbd.
|
|
FLTINT If true, use the floating-point exception interrupts to detect
|
|
errors and overflows on FP operations. The interrupt sets a
|
|
global error flag. Otherwise, calls library routines to see
|
|
the condition code from each operation. For SPARCs, it's not
|
|
clear that the interrupt trick works, because of code re-
|
|
arrangement by the C compiler.
|
|
BUFFER Used (apparently) only in testdisplay.c to decide if it should
|
|
read the sysout directly, or buffer each page.
|
|
|
|
IFPAGE_DEFINED Used in .h files to prevent redefinition of Interface page.
|
|
IOPAGE_DEFINED " for IO page definition.
|
|
NOWAY Used to dike out C definitions of RPLACA and RPLACD in the
|
|
file car-cdrmacro.h
|
|
XWINDOW True if compiling for an X-windows emulator.
|
|
|
|
BIGATOMS True if this emulator will support 3-byte symbols, instead of
|
|
the old, 2-byte atom numbers.
|
|
|
|
NEWBITBLT True if we want to use assembler BITBLT code, rather than
|
|
have code created inline by macro calls.
