Subject: [PATCH 1/2] gdb: Fix reading of partial symtabs in dbxread.c
Date: Tue, 4 Apr 2023 17:59:14 +0000 [thread overview]
Message-ID: <20230404175915.288558-2-thiago.bauermann@linaro.org> (raw)
In-Reply-To: <20230404175915.288558-1-thiago.bauermann@linaro.org>
After commit 9675da25357c ("Use unrelocated_addr in minimal symbols"),
aarch64-linux started failing gdb.asm/asm-source.exp:

PASS: gdb.asm/asm-source.exp: look at static function
The problem is simple: a pair of parentheses was removed from the
expression calculating text_end and thus text_size was only added if
lowest_text_address wasn't equal to -1.
This patch restores the previous behaviour and fixes the testcase.
Tested on native aarch64-linux.
