digitalmars.D - Godbolt.org hex view

reply Walter Bright <newshound2 digitalmars.com> writes:
When I used to use godbolt.org, it would show the assembler generated by the 
compiler along with the hex bytes. Now it no longer shows the hex bytes. It
just 
shows the disassembly. How do I turn that on? I clicked on every option I could 
find. I googled it. No joy. I tried Groc. No useful information.

P.S. I get the hex output with clang, but not with gcc???

"Output" + check "Link to binary"

e.g https://godbolt.org/z/41hneYz98

It seems that hex is only displayed when objdump is also used as 
disaseembler, otherwise without the "Link to binary" option an 
".S" file is directly produced.

Thank you, your link works. But where does it say "Link to binary" ??

Under the compiler/target drop down button.

There is a drop down button called Output.

There is no Compiler/target button. But there is a dialog box with "ARM64 GCC 
10.2.0".

There's one with a gear on it that has:

- Compile to binary object (greyed out)
- Execute the code (greyed out)
X Intel asm syntax (greyed out)
X Demangle identifiers

With the first 3 options greyed out.


Now, merely changing the target to "armv8-a clang (trunk)":

- Compile to binary object (greyed out)
X Link to binary
- Execute the code
X Intel asm syntax
X Demangle identifiers


and the hex code appears. All I did was change the compiler and target.

Yeah that's it.

The gear is the icon for a button with the label "Output".

Here is how it is supposed to look like:

The reason not all targets may be showing up as an option is based upon 
the host system may not have everything installed that is needed to link 
for each target. Which can be annoying.

I don’t think so:


 Error 1011

 The owner of this website (cattermole.co.nz) does not allow 
 hotlinking to that resource (/godbolt.org.example.png).

Oh lol, disabled that on cloudflare.

Worked when I had typed it in, didn't check for referrals.

I found that the hex view appears and disappears even with the exact same 
compiler selected. I filed a bug report, but that went nowhere.

Yeah sometimes settings get lost and default isn't what you expect of 
it, depending on what instances you access.

Can be annoying if you have to mess with something just the one time.

Ah, I found it. It's under the "gear" icon. I hate icons. But I'm glad to be 
back in business with godbolt.

What do you mean icon?

How small is your resolution that it can't display the label?

But with the ARM64 GCC compilers, the "Compile to binary object" is greyed out! 
Arrgghhh
