-Subject: [PATCH] bn_mul.h: fix x86 PIC inline ASM compilation with GCC < 5
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-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.
-
-Upstream-Status: Backport [https://github.com/Mbed-TLS/mbedtls/commit/c0546e351f6d7ab50eb1de8cef1d0d167760fccc]
