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 Smiley
Thank you very much in advance! Smiley

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  Smiley
I guess there's only a matter of time before XC16 needs the same treatment...

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

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
Quote
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 !!

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.
