Bug ID: 41246
Summary: Compilation time is incredible slow
Product: clang
Version: unspecified
Hardware: Other
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]

I have compiled 2.5MB of C source code with clang 5.0 and 9.0.
Machine: ARM64 quadcore CPU, with 4GB RAM and SSD of 1TB.
Compiling with optimizations ON (-O2)
Compiler Time
lcc 8.7 seconds
gcc 2minutes 30 seconds
clang 5.0 26 minutes
clang 9.0 32 minutes
This is just unbearable and makes clang unusable.
Thanks in advance for your attention.
