What are the correct .cpu, .fpu Assembly entries for the Raspberry Pi 4

Question

I want to learn ARM Assembly for the Raspberry Pi, I found out that the following versions of the Raspberry Pi are using the listed cpu-fpu version, could anyone please tell me:

1. what the Raspberry Pi 4 is using as cpu-fpu (I guess cpu is cortex-a72)
2. where to find the exact cpu fpu specifications (I googled for the official ARM specifications but I could not find the fpu in the docs)?

Rasperry Pi:

• Zero
• 1A+
• 1B+

uses

• cpu: arm1176jzf-s
• fpu: vfp

the Raspberry Pi:

• 2B

uses

• cpu: cortex-a7
• fpu: neon-vfpv4

and the Raspberry Pi:

• 3B

uses

• cpu: cortex-a53
• fpu: neon-fp-armv8

After a more in depth search I found another source which answered my question. I combined the relevant entries in the following table.

|---------------------|------------------|------------------|
| Raspberry Pi        | .cpu             | .fpu             |
|---------------------|------------------|------------------|
| Zero                | arm1176jzf-s     | vfp              |
| 1 A+                |                  |                  |
| 1 B+                |                  |                  |
|---------------------|------------------|------------------|
| 2 B                 | cortex-a7        | neon-vfpv4       |
|---------------------|------------------|------------------|
| 3 B                 | cortex-a53       | neon-fp-armv8    |
|---------------------|------------------|------------------|
| 4 B                 | cortex-a72       | neon-fp-armv8    |
