555282497c Removed --lib option from cl65. 
The general approach of cl65 when generating the command lines to be executed is to first put options and the put files. However, this doesn't work well with the --lib option which would rather need to be put when libraries in general are put. I opted to not add this special behavior to cl65 as
* the use case for the --lib option is _VERY_ specific
* cl65 is after all a wrapper for ordinary use cases

fb0d09a277 Changed sim65's internal error codes from 9-bit values to 7-bit values. 
Some shells truncate process return codes to 8 bits.  And, the eigth bit often is used to show that a signal stopped the process.

a0db846a97 Allowed old-style (K and R) function declarations to be fastcall. 
That lets them match old-style definitions.  It avoids "Type conflict" error messages.  It allows shorter function calls.

Fixed the types of some variables in "test/ref/otccex.c".  It avoids crashes on 64-bit Windows (32-bit Windows with 64-bit pointers).

2f3955dbc7 src/Makefile: Simplify BUILD_ID logic. 2019-07-15 12:42:48 +02:00
Greg King
28584b31f1 Made the ld65 configure file's segment offset attribute accept zero as a value. 
Expressions are allowed as values.  Therefore, zero might be set explicitly by some conditions.
 2019-06-30 22:44:10 -04:00
Björn Esser
83e0c70de5 Replace GIT_SHA with a more versatile BUILD_ID definition. 
When compiling cc65, it will by default place the git hash (if available) of
the checked out commit in the version string.  This isn't useful when building
a package for a Linux distribution, since there either won't be an upstream
git hash if there is one at all.

Thus we replace GIT_SHA with a more versatile BUILD_ID, which can be defined
to any arbitrary string.  When building, its contents will be appended to the
version string instead of the git hash.

If BUILD_ID is not defined by the user the behaviour will be exactly the same
as before.  That means BUILD_ID gets automatically defined to Git <GIT_SHA>,
if it can be determined from a checkout.

ac2ecb0b2c 65816 now generate EXPR_NEARADDR instead of EXPR_WORD0 for default assumed address mode, which will be validated by the linker's range check rather than blindly truncated. Assuming the assembler correctly validated this, the linker is allowed to truncate. 2019-05-11 12:32:44 +02:00

12fbdbf418 sim65: S_IREAD and S_IWRITE are nonstandard. 
The Linux build was failing with:

sim65/paravirt.c: In function ‘PVOpen’:
sim65/paravirt.c:217:18: error: ‘S_IREAD’ undeclared (first use in this function)
         OMode |= S_IREAD;

aba320eade Allow "mode" argument to open() to be passed from 6502 code. 
Implements this suggestion:

d602572bbe Fix permissions for files created by sim65. 
Files created by my programs running under sim65 had really weird permissions:
--w-r--r-x  1 ppelleti  staff  19 Aug 16 23:22 json.test.print.tmp

So, for example, my program running under sim65 was not able to read
the file it had just written.

This is because the third argument to open (mode) was not being
specified in paravirt.c, so it was just picking up random crud off the
stack to use as the mode.

I added a mode of 0666, and now my program runs correctly.

ad6c2dbe7b Added code to make the 65816's MVN and MVP instructions handle both immediate (bank) and far-address operands. 2018-07-29 03:50:02 -04:00

eeb1b927ce Fixed the order in which the 65816's block-move instructions' operands are written and assembled. 
The source bank number is written first; but, assembled second.
The destination bank is written second; but, assembled first.

b74ab9de89 Allow spaces in path names. 
The Microsoft C Library needs to have spawnvp() parameters with spaces quoted manually. We do this only if actually necessary to limit issues with parameters already containing double quotes.

d861be8ad5 Escape spaces in target path. 
cc65 escapes spaces in paths it writes to dependency files (see WriteEscaped() in cc65/input.c). Given that the output of OptPrintTargetPath() is supposed to be used in Makefiles in pretty much the same way it is appropriate to escape spaces here too.
