MPLAB xc32 v1.10 has been release

http://www.microchip.com/mplabxc32windows

New Features in MPLAB® XC32 v1.10

Support for C++

Standard C++ Library

[marcodassi]

Just downloaded XC8, XC16 and XC32 1.10; tested with current fix; results:

- XC8 1.10 - fine, works in Pro mode with all optimizations;
- XC16 1.10 - fine, works in Pro mode with all optimizations;
- XC32 1.10 - DOESN'T WORK - the compiler stays in Free mode, no optimizations allowed

I've tried to copy xclm.exe in the "\Program Files\Microchip\xc32\v1.10\bin" folder too, with no luck.

Please fix it, if possibile
Thank you very much in advance!

XC32 1.21 is out!

http://www.microchip.com/mplabxc32windows

testing medicine...

[marcodassi]

seems to work
BTW, no major improvements in 1.21... "only" new parts, header & linker scripts updates

[Catcatcat]

released a new version Windows (x86/x64) MPLAB® XC32 Compiler v1.22

[Manuel]

FYI: released a new version Windows (x86/x64) MPLAB® XC32 Compiler v1.30

Manuel.

[marcodassi]

Manuel: Thank you, but: where is it?

edit: found! on the mchip site (but is still listed as 1.22)

[Catcatcat]

Do not believe what is written, and just click and you will be happy

[Catcatcat]

MPLAB® XC32 Compiler v1.31 !!!

[Manuel]

FYI: released a new version Windows (x86/x64) MPLAB® XC32 Compiler v1.32

'njoy

[marcodassi67]

They check for modified xclm file as is in latest XC32 release.

hello petarp, you mean latest xclm doesn't work with XC32? I've tried it some time ago and it seems working,,,

[petarp]

Hi marcodassi67, Yes XC32 v1.32 checks for modified "xclm" file.
Here is the fix for XC32:
 1. Open "C:\Program Files\Microchip\xc32\v1.32\bin\bin\gcc\pic32mx\4.5.2\cc1.exe" file with hex editor.
 2. Find these bytes "75 6a 89 5d" and replace first two bytes with "90" ("90 90 89 5d").
 3. Do same with "C:\Program Files\Microchip\xc32\v1.32\bin\bin\gcc\pic32mx\4.5.2\cc1plus.exe" and "C:\Program Files\Microchip\xc32\v1.32\bin\bin\gcc\pic32mx\4.5.2\lto1.exe" files.
 4. And use latest "xclm" file from here.
It works for C++ too.

Regards.

And here is the patcher for XC32. Great work, petarp  
I guess there's only a matter of time before XC16 needs the same treatment...

[juvann]

Now xc32 calculate the sha256sum of file xclm.
In linux version the sum of origina xclm is 4fae1d53570ebffe637d8c5f77789ecbe690f67af65d0e3af8474bfee479239e
with a perl command with can replace it with new sum

Code:

sha256sum /opt/microchip/xc32/v1.32/bin/xclm
perl -pi -e 's/4fae1d53570ebffe637d8c5f77789ecbe690f67af65d0e3af8474bfee479239e/NEW VALUE OF SHA256SUM/g' /opt/microchip/xc32/v1.32/bin/bin/gcc/pic32mx/4.5.2/cc1
perl -pi -e 's/4fae1d53570ebffe637d8c5f77789ecbe690f67af65d0e3af8474bfee479239e/NEW VALUE OF SHA256SUM/g' /opt/microchip/xc32/v1.32/bin/bin/gcc/pic32mx/4.5.2/cc1plus

[Catcatcat]

MPLAB® XC32 Compiler v1.34

[frnando]

Sorry, but the patcher/xclm is still working with v1.33?
Thanks.

[bluex]

v1.34 cannot be activated with provided medecine. read details here

New XC32 1.40

[Manuel]

Even updated 1.40 XC32 part support

https://www.microchip.com/mplabxc32-ps-windows

[Armageddon]

Fix for XC32 v1.40.

Steps:
 1. Open "C:\Program Files\Microchip\xc32\v1.40\bin\bin\gcc\pic32mx\4.8.3\cc1.exe" file with your favorite hex editor.
 2. Find and replace these bytes "0F 85 CC 00 00 00 8D 44" with "90 E9 00 00 00 00 8D 44".
 3. Do same with "C:\Program Files\Microchip\xc32\v1.40\bin\bin\gcc\pic32mx\4.8.3\cc1plus.exe" and "C:\Program Files\Microchip\xc32\v1.40\bin\bin\gcc\pic32mx\4.8.3\lto1.exe" files.
 4. Use latest "xclm" file from here, i.e:

xclm

Code:

int main(){
    return 2;
}

Tested under Windows 10 and MPLAB X IDE v3.15.

More info: http://www.jubatian.com/articles/turning-on-optimizations-in-microchips-xc32/

Note: I used the same technique that petarp, but now:

90 = nop
E9 = jmp
00 00 00 00 = $ + 5

Cheers.

Update MPLAB® XC32 v1.44

Fixed in v1.44

XC32-720
In the MPLAB XC32 v1.43 release, the linker incorrectly treated all symbols in the input object files as weak. This meant that non-weak symbols could not override weak symbols. The correct behavior of weak and non-weak symbols has been restored.
XC32-709
When compiling and linking with Smart IO and the Legacy Libc, printf() and related functions may print incorrect output. Under some conditions, the format specifier could get printed. This issue has been fixed.
XC32-708
In XC32 v1.43 and earlier, When compiling and linking with the Non-Legacy Libc, printf() and related functions did not handle the %ll conversion specifier correctly when the value has non-zero bits in the upper 32-bit positions.
XC32-707
XC32 v1.43 emitted a linker error when applying the coherent attribute to a zero-sized section. (Ex: uint8_t __attribute__((coherent)) ary[0]; ) The linker now emits an error when it can't allocate only non-zero sized sections.

The medicine works !!

[Git]

Any medicine for XC32 2.05 please?

[Catcatcat]

Compared the work of version 1.44 and 2.05
- 3 - Optimize yet more favoring speed
medicine "standard" 

as for my project, it makes no difference, everything works!

[Git]

I looked with a magnifier, but still no difference to see

Plenty of    0F 85 CC 00 00 00 xx xx
but no       0F 85 CC 00 00 00 8D 44

[tumbleweed]

I don't know about the patch shown here, but the medicine in the 'XC - software only' thread appears to work for XC32 2.05

http://www.sonsivri.to/forum/index.php?topic=44014.0

[adamantium]

Any medicine for XC32 2.05 please?

I can also confirm the old xclm.exe works, just rename the one in the /bin directory to xclm.old, copy in the xclm.exe patcher and run as administrator.

[MetaMetal]

xc32 v2.15 is out.
medicine works fine.

[Catcatcat]

MPLAB® XC32/32++ Compiler v2.20 (link to the latest compiler version)

everything is working!

[Catcatcat]

MPLAB® XC32/32++ Compiler v2.40 (link to the latest compiler version)

everything is working!

[Manuel]

updated to MPLAB® XC32/32++ Compiler v2.41

Thank you , still perfect.

X!

[Catcatcat]

MPLAB® XC32/32++ Compiler v2.50 (link to the latest compiler version)

everything is working!

On my projects, the new version of the compiler has shown an improvement in optimization for data in RAM (packs 1.2.51).
