+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.
