Kconfig detects recursive dependencies in a choice block, but the error
message is unclear.
[Test Code]
choice
prompt "choose"
depends on A
config A
bool "A"
config B
bool "B"
endchoice
[Result]
Kconfig:1:error: recursive dependency detected!
Kconfig:1: choice <choice> contains symbol A
Kconfig:5: symbol A is part of choice <choice>
For a resolution refer to Documentation/kbuild/kconfig-language.rst
subsection "Kconfig recursive dependency limitations"
The phrase "contains symbol A" does not accurately describe the problem.
The issue is that the choice depends on A, which is a member of itself.
The first if-block does not print a sensible message. Remove it.
This commit improves the error message to:
Kconfig:1:error: recursive dependency detected!
Kconfig:1: symbol <choice> symbol is visible depending on A
Kconfig:5: symbol A is part of choice <choice>
For a resolution refer to Documentation/kbuild/kconfig-language.rst
subsection "Kconfig recursive dependency limitations"
