Guide to attaching to Chrome with RenderDoc (for WebGL 2 and WebGPU)

1. Set the environment variable RENDERDOC_HOOK_EGL to 0. I use the Windows Settings to set this in my User Environment Variables.
2. Launch RenderDoc
3. In RenderDoc, navigate to Tools -> Settings, then on the General page, check "Enable process injection (restart required)". Restart RenderDoc.
4. Grab a copy of WinPixEventRuntime.dll from https://devblogs.microsoft.com/pix/winpixeventruntime/ (rename the .nupkg to a zip, it's in bin/x64), and copy it over to %LocalAppData%\Local\Google\Chrome SxS\Application\$CurrentVersion. Unfortunately this step needs to be repeated every time Chrome updates, since it wipes the current directory. Would be nice if it shipped with Chrome Canary / Chrome Dev (or was statically linked into Chrome)
5. Launch Chrome with the arguments `--disable-gpu-sandbox --gpu-startup-dialog --disable-direct-composition=1 --enable-dawn-features=use_user_defined_labels_in_backend,emit_hlsl_debug_symbols,disable_symbo

In your effort of implementing standalone-ha with keycloak postgresql using JDBC_PING you will stumble upon many sites that define 
the table structure for jgroupsping and the right one goes like this -

CREATE TABLE IF NOT EXISTS JGROUPSPING (
                   own_addr varchar(200) NOT NULL,
                   cluster_name varchar(200) NOT NULL,
                   ping_data BYTEA,
                   constraint PK_JGROUPSPING PRIMARY KEY (own_addr, cluster_name)
                   );

Notes

It should be noted that:

1. Basic blocks in SSA can be identified at 3 points:

• Start of the program
• Labels
• Branches

2. Basic blocks are used in optimisation.

max(-x,-y) = -min(x,y)
min(-x,-y) = -max(x,y)

abs(x) = abs(-x)
abs(x) = max(x,-x) = -min(x,-x)
abs(x*a) = if (a >= 0) abs(x)*a
              (a <  0) -abs(x)*a

// basically any commutative operation
min(x,y) + max(x,y) = x + y
