Subject: [PATCH] bn_mul.h: fix x86 PIC inline ASM compilation with GCC < 5

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