I implemented a feature to show location info with a new line in diagnostics.
This patch intends to make diagnostics much clearer by displaying location info with a new line and putting a line break between each diagnostic.
Before this patch:
test2.c:4:12: error: expected identifier or '(' int [5] *; ^ test2.c:4:12: error: brackets are not allowed here; to declare an array, place the brackets after the identifier int [5] *; ~~~~ ^ ()[5] 2 errors generated.
This patch brings it to:
error: expected identifier or '(' --> test2.c:4:12 int [5] *; ^ error: brackets are not allowed here; to declare an array, place the brackets after the identifier --> test2.c:4:12 int [5] *; ~~~~ ^ ()[5] 2 errors generated.
Also, if this patch is used with -fdiagnostics-show-line-numbers which is implemented in https://reviews.llvm.org/D125078:
error: expected identifier or '(' --> test2.c:4:12 4 | int [5] *; | ^ error: brackets are not allowed here; to declare an array, place the brackets after the identifier --> test2.c:4:12 4 | int [5] *; | ~~~~ ^ | ()[5] 2 errors generated.
