| Subject: kbuild: consolidate redundant sed script ASM offset generation |
| |
| From: Masahiro Yamada <yamada.masahiro@socionext.com> |
| |
| commit 7dd47b95b0f54f2057d40af6e66d477e3fe95d13 upstream. |
| |
| This part ended up in redundant code after touched by multiple |
| people. |
| |
| [1] Commit 3234282f33b2 ("x86, asm: Fix CFI macro invocations to |
| deal with shortcomings in gas") added parentheses for defined |
| expressions to support old gas for x86. |
| |
| [2] Commit a22dcdb0032c ("x86, asm: Fix ancient-GAS workaround") |
| split the pattern into two to avoid parentheses for non-numeric |
| expressions. |
| |
| [3] Commit 95a2f6f72d37 ("Partially revert patch that encloses |
| asm-offset.h numbers in brackets") removed parentheses from numeric |
| expressions as well because parentheses in MN10300 assembly have a |
| special meaning (pointer access). |
| |
| Apparently, there is a conflict between [1] and [3]. After all, |
| [3] took precedence, and a long time has passed since then. |
| |
| Now, merge the two patterns again because the first one is covered |
| by the other. |
