really bad news :( i tryed to decompile BOOT.BIN, with small success, only 2-3 functions decompiled, looks like the app decompiles GP and exports only? how do u think, it's possible to add arbitrary address to command line instead GP, because GP in boot.bin just start main thread and exit !? i cann...

Man, I repeat: PSP IS BIG-ENDIAN.

That said, almost all RISC processors are big-endian. But MIPS is both-endian anyway xD

Man, you're totally wrong, PSP is little endian like PC.

Wally wrote:Then again, you'd have to consider the endianess. PSP is Little Endian and PC is big endian.

you are not well informed :P. PC and PSP are little endian.

what is interesting you is probably psplibdoc. It is a an XML file which contains NID and names of functions. PRXTOOLS can produce IDA map file and can resolve names and reference with psplibdoc.

OK, so the reference I found is old... :( On the PS1 the scratchpad was a great place to build stuff. Is that not the case on PSP? I hope the extra 16K solves the OP's problem :D Jim Indeed, it is useless if the goal is for performance because this scratch pad is not connected directly to CPU but i...

Jim wrote:Scratchpad is 4Kb of fast memory at 0x100000.

Jim

"fast" memory ? are you kidding :P ? it is 16 KB and not 4 KB and surely not fast the way it is connected to bus.

no, i didn't. I don't know all the details about pspdecompiler source enough to solve those problems. I also noticed that constant return values are not always treated (I was forced to use prxtool to retrieve some return values). Have you any plan to handle float as well ? their handling is quite si...

pspdecompiler has trouble with tail call. int f(int a) { return g(a); } f will call g through a J instead of JAL, and it seems f is not reckoned properly because of this. J can be considered as a call if it has the same arguments and result registers and the callee is defined as a function. So this ...

Ive read document The Naked PSP paragraph of Vector Processor, sentence "128 32bits registers".
Dose this mean 128 pieces of 32bits registers?

VFPU has 8 banks of 16 registers ==> 128 registers. It does mean you can use up to 128 float scalar registers

Thanks for the reply hlide. Replaced the psp-gcc with psp-g++ from the windows-> preferences, created completely new project with same content in .c file and in MakeFile. Reports exactly the same error. But one thing I noticed and I don't know is it supposed to be this way. When I hit build this is...

replace psp-gcc with psp-g++ in the configuration

i had the same problem

boost4PSP now includes boost::filesystem !? I asked if boost::filesystemcan be included a long time ago. Up to now, I thought it was an abandoned project.

I think so as I cannot see the bugs I used to see any longer :)

When doinga "pull", I got this : git.exe pull "origin" remote: Compressing objects: 100% (17/17) [K remote: Compressing objects: 100% (17/17), done.[K remote: Total 26 (delta 13&#4...

ackonwledged. I'll try when i have time and when I'm getting familiar with GIT :/ (which action you should do like a Update SVN ?)

bug with counters in loops is still unresolved : while &#40;1&#41; &#123; var17 = var17; <-- it should be &#58; "var17 = var17 + 0x00000001;" InterruptManagerForKernel_7527A9BA &#40;0x00000019, 0x00000000, 0x00000001&#41;; if &#40;&#40;&#40;var17 < 0x000...

do you detect some functions not terminating with a JA $RA but with a J ? the rule is to check if a subroutine has no forward conditional branch when you meet a J to conclude this is subroutine with a tail call to another subroutine : void X&#40;&#41; &#123; ...; Y&#40;&#41;; &am...

I tried your last revision : two comile-time errors about value_append function missing the last argument in ssa.c; I appended FALSE as last argument to build pspdecompiler fine.

And yes, I have no crash now with all the prx which crashed.

there is a regression on the last version, pspdecompiler crashes on some prx files whereas the first public version did not.

@hnaves There is a problem : in a loop starting with "while (1)" with a register counter, i have : "varN = varN;" instead of "varJ = varI + CONSTANT;" where varI is containing a constant. It seems the issue is in output.c : void print_operation &#40;FILE *out, struc...

@SilverSpring: correct --> http://forums.ps2dev.org/viewtopic.php?p=80416#80416

quite impressive

do you think we can put it through SVN in google code ? so some of use can contribute ?

I heard gcc 4.4.0 has better overall optimization.

just give us the disassembly output AFTER hooking this function and may be we could help you.

you seem to execute an VFPU instruction in a thread where THREAD_ATTR_VFPU was not set. Which is weird since you seem to be in the main thread. :/

I found the example posted by Hlide but I really couldn't make anything out of it. I did my own little patch of the functions for jumping to my own functions, and tried to change memory flags to allow linking to a kernel function of mine. This didn't work. So I'd be glad if you could post a little ...

Edit - as for your interpretation of the asm, it's wrong aswell. a1 and a2 are never - used in a reading way... only for storage. Do you want a MIPS fight with me :) ? you're wrong indeed. Why ? SW $a2, ... means store the content of $a2 in a memory place. Now $a2 is either a temporary register or ...

About the stepping issues, I have the same issue and also get it if I debug native applications, so I guess... it is again either some bug on gdb or the eclipse gdb frontend, but I need to look into it further... yes, those are the left issues with Eclipse debug (and when I don't run FireFox of cou...
