| Subject: | Re: [PATCH v3 4/9] dump: Remove the section if when calculating the memory offset |
| Date: | Thu, 31 Mar 2022 12:56:47 +0400 |
When s->shdr_num is 0 we'll add 0 bytes of section headers which is
equivalent to not adding section headers but with the multiplication
we can remove a if/else.
