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.

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

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.

xc32 v2.15 is out.
medicine works fine.

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

everything is working!

[Catcatcat]

everything is working!

[Manuel]

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).

MPLAB XC32 32++ Compiler 3.00

Just tested with the "classic" medicine... no luck this time - the patch crashes cc1.exe

BTW, there are some undocumented changes... specifically, in the gcc options, some of them have changed name

[Catcatcat]

And V3.0 did not work for me

I just tested my fix with a simple XC32 v3 project and it seems to work fine.

Tell me how to reproduce this issue.

[danymogh]

Here use this medicine, it should work for all future V3.xx as well

[Catcatcat]

Here use this medicine, it should work for all future V3.xx as well

also, pray for me to become rich.

Thank you very much! The vaccine works!
To work, I additionally had to update .NET 5.0 Desktop Runtime (v5.0.6) https://dotnet.microsoft.com/download/dotnet/thank-you/runtime-desktop-5.0.6-windows-x64-installer

yes, sorry I forgot to mention you need .net 5 or above runtime to run the SHA-Patcher

[marcodassi]

Thank you very much, danymogh!

Does this medicine works for XC8 and XC16 too, or is for XC32 only?

> also, pray for me to become rich.
Done, are you rich now?

Best regards

Hi.

Is the medicine compressed or has only the file extension been changed?

It doesn't work for me.

Hi.

It has been compressed, sorry for the misunderstanding. It has worked correctly.

Regarding the new version (3.xx), there are changes in the concept of the C language.

My projects without harmony v2 or v3 compile perfectly with version XC32 v3.00, but those who use that tool, the compiler gives errors. Any suggestions what can be done?

[Catcatcat]

I was unable to activate version 3.01. Who managed to accomplish this? Please share.

[Top]

My fix seems to work okay on v3.01 too.

Tell me how to reproduce this issue.

[danymogh]

I was unable to activate version 3.01. Who managed to accomplish this? Please share.

my fix , like i said , should work for all 3.xx version and i checked for 3.01 and it still works.
do a clean install and it should fix any problem
