4 | Subject: [PATCH] bn_mul.h: fix x86 PIC inline ASM compilation with GCC < 5 | ||
5 | MIME-Version: 1.0 | ||
6 | Content-Type: text/plain; charset=UTF-8 | ||

9 | Fixes #1910 | ||
10 | |||
11 | With ebx added to the MULADDC_STOP clobber list to fix #1550, the inline | ||
12 | assembly fails to build with GCC < 5 in PIC mode with the following error: | ||
13 | |||
14 | include/mbedtls/bn_mul.h:46:13: error: PIC register clobbered by ‘ebx’ in ‘asm’ | ||
15 | |||
16 | This is because older GCC versions treated the x86 ebx register (which is | ||
17 | used for the GOT) as a fixed reserved register when building as PIC. | ||
18 | |||
19 | This is fixed by an improved register allocator in GCC 5+. From the release | ||
20 | notes: | ||
21 | |||
22 | Register allocation improvements: Reuse of the PIC hard register, instead of | ||
23 | using a fixed register, was implemented on x86/x86-64 targets. This | ||
24 | improves generated PIC code performance as more hard registers can be used. | ||
25 | |||
26 | https://www.gnu.org/software/gcc/gcc-5/changes.html | ||
27 | |||
28 | As a workaround, detect this situation and disable the inline assembly, | ||
29 | similar to the MULADDC_CANNOT_USE_R7 logic. | ||
30 | |||
