MasterDuke indeed, nine++ 11:20
nine: btw, i assume you've seen the appveyor failures? `src\core\interp.c(5553) : error C2275: 'MVMuint64' : illegal use of this type as an expression src\moar.h(45) : see declaration of 'MVMuint64'src\core\interp.c(5553) : error C2146: syntax error : missing ';' before identifier 'value'src\core\interp.c(5553) : error C2065: 'value' : 11:22
undeclared identifier`
nine MasterDuke: no, where do I see those? 11:33
MasterDuke ci.appveyor.com/project/samcv/moar...uldqtigutr
nine Oh, I think it's about mixing declarations and statements 11:34
So...how do we configure AppVeyor to compile in a way that those aren't an issue anymore?
MasterDuke i thought we don't allow that (mixing declarations and statements) anywhere? 11:37
nine Well, I've had it with that nonsense. I removed the error in an attempt to fix the build on older compiler versions, which it did: github.com/MoarVM/MoarVM/commit/a0...960f257bf6 11:44
Now I'm looking for the switch to enable C99 support on MSVC
Geth MoarVM: 21f9c3284b | (Stefan Seifert)++ | build/setup.pm
Try to enable C99 features on MSVC
11:58
nine Fails, because that switch is only available in VS 2017 and AppVeyor builds on VS 2015. The build on 2017 is disabled because we don't know where "setenv.cmd" is 12:04
Geth MoarVM: 3d2f8d739f | (Stefan Seifert)++ | .appveyor.yml

Avoid empty initializers to help syntactically challenged compilers

The last field is an array, so at least give it the initial 0 (which it will replicate onto the remaining slots)
12:18
nine There we have it! Never again write worse code just to appease ancient versions of compilers limited by their vendor's politicking :) ci.appveyor.com/project/samcv/moar...p018c6qdtq 12:24

The && was indeed intended and the expression is correct. Sorry jnthn

12:38
MoarVM: 31a1b22c6c | (Stefan Seifert)++ | build/setup.pm
Enable -Wall with only a few exceptions

The exceptions are:
  -Wunused-parameter which would generate lots of warnings about parameters that
   are not used by all implementations of an interface.
  -Wunused-function which would generate lots of warnings about static inline
   functions defined in header files but not used by all files that include the
   header.
  -Wmissing-braces which would generate lots of apparently bogus warnings. Might
   be due to a compiler bug.

Geth MoarVM: 5464dd47ce | (Stefan Seifert)++ | 4 files
Move internal shift_jis functions to shiftjis.c and mark them static

This fixes compiler warnings about unused variables caused by them getting declared static in a header file that was included in 2 .c files. The functions in question were used only in shiftjis.c, so move them there.
13:08
nine So that's it. Only 3 warnings left which I'm not sure what to do about. 13:09

nine dogbert17: that doesn't make any sense, as gb2312 is now a char *, i.e. signed. So why would a comparison vor >= 0 be always true? 21:01

dogbert17 nine: "char is signed on Intel and unsigned on ARM (the Pi)" according to answer on www.raspberrypi.org/forums/viewtop...p?t=233557 21:21
lizmat YUK
dogbert17 could that be the reason assuming that the information in the link is correct?
nine WHAT? 21:23
dogbert17 shocking ? 21:24
lizmat to me that is a WAT
stackoverflow.com/questions/205493...by-default 21:25
"The standard does not specify if plain char is signed or unsigned" 21:26
MasterDuke then maybe we should add `-fsigned-char` to the compiler options for rpi 21:27
dogbert17 MasterDuke: perhaps for other systems as well: "This causes problems on ARM based machines since "char" is of the "unsigned" variety, which allows the compiler to generate faster, more efficient code. ARM is not alone in this - SGI Mips running IRIX also encounters this problem."
Dunno if those systems are still in use 21:28
the Irix stuf that is
lizmat so why do we assume chars are signed? wouldn't it be better to thing of them as unsigned ? 21:29
nine I think the best course of action is to revert my changes to that file and just disable the warning. It's quite ironic that it's the same warning that now pointed out correctly that the code is wrong. Previously it read if (0 <= gb2312[i] && gb2312[i] <= 127) which covers both the signed and unsigned cases but will do one superfluous check in any case 21:30
dogbert17 nine: it was two files
japhb lizmat: Not looking at that particular code, so this could be unrelated, but don't we use negative values for signed char/short/int in strings to indicate that we've created an artificial combined grapheme "codepoint" to allow fast string indexing by grapheme? 21:32
dogbert17 gb2312.c and gb18030.c
lizmat yeah, but those are 32-bit ints
I believe?
japhb lizmat: I thought we did an 8-bit form as well for efficiency with european codepages? 21:33
To whit, making latin-1 fast
lizmat ah, in that case, it's above my pay level
japhb It's a vague memory for me as well.
nine negative graphemes are synthetics, but that's distinct from our 8-bit encoding handling 21:34
Will push a fix tomorrow 21:35
