From 82d983826243d6a3163bb4fa4761d864e8acc339 Mon Sep 17 00:00:00 2001 From: Peter Wemm Date: Sun, 24 Oct 2004 06:34:13 +0000 Subject: Essentially a NOP commit. The xpcom reflect patches for amd64 support are now present in the firefox source tree, but with one bug fix compared to the old version we provided. Use their version. --- ...h-xpcom-reflect-xptcall-src-md-unix-Makefile.in | 2 +- www/firefox-esr/files/patch-xptcall-amd64 | 388 --------------------- 2 files changed, 1 insertion(+), 389 deletions(-) delete mode 100644 www/firefox-esr/files/patch-xptcall-amd64 (limited to 'www/firefox-esr') diff --git a/www/firefox-esr/files/patch-xpcom-reflect-xptcall-src-md-unix-Makefile.in b/www/firefox-esr/files/patch-xpcom-reflect-xptcall-src-md-unix-Makefile.in index c0af6bf2df9d..5276b54f0a1a 100644 --- a/www/firefox-esr/files/patch-xpcom-reflect-xptcall-src-md-unix-Makefile.in +++ b/www/firefox-esr/files/patch-xpcom-reflect-xptcall-src-md-unix-Makefile.in @@ -7,7 +7,7 @@ $FreeBSD$ CPPSRCS := xptcinvoke_unixish_x86.cpp xptcstubs_unixish_x86.cpp endif +ifeq (amd64,$(OS_TEST)) -+CPPSRCS := xptcinvoke_amd64_freebsd.cpp xptcstubs_amd64_freebsd.cpp ++CPPSRCS := xptcinvoke_x86_64_linux.cpp xptcstubs_x86_64_linux.cpp +endif endif # diff --git a/www/firefox-esr/files/patch-xptcall-amd64 b/www/firefox-esr/files/patch-xptcall-amd64 deleted file mode 100644 index 541d40207aa7..000000000000 --- a/www/firefox-esr/files/patch-xptcall-amd64 +++ /dev/null @@ -1,388 +0,0 @@ -$FreeBSD$ - ---- /dev/null Wed Dec 31 16:00:00 1969 -+++ xpcom/reflect/xptcall/src/md/unix/xptcinvoke_amd64_freebsd.cpp Thu Oct 16 22:59:43 2003 -@@ -0,0 +1,174 @@ -+/* -*- Mode: C; tab-width: 8; indent-tabs-mode: nil; c-basic-offset: 4 -*- */ -+// Platform specific code to invoke XPCOM methods on native objects -+ -+#include "xptcprivate.h" -+ -+// 6 integral parameters are passed in registers -+const PRUint32 GPR_COUNT = 6; -+ -+// 8 floating point parameters are passed in SSE registers -+const PRUint32 FPR_COUNT = 8; -+ -+// Remember that these 'words' are 64-bit long -+static inline void -+invoke_count_words(PRUint32 paramCount, nsXPTCVariant * s, -+ PRUint32 & nr_gpr, PRUint32 & nr_fpr, PRUint32 & nr_stack) -+{ -+ nr_gpr = 1; // skip one GP register for 'that' -+ nr_fpr = 0; -+ nr_stack = 0; -+ -+ /* Compute number of eightbytes of class MEMORY. */ -+ for (uint32 i = 0; i < paramCount; i++, s++) { -+ if (!s->IsPtrData() -+ && (s->type == nsXPTType::T_FLOAT || s->type == nsXPTType::T_DOUBLE)) { -+ if (nr_fpr < FPR_COUNT) -+ nr_fpr++; -+ else -+ nr_stack++; -+ } -+ else { -+ if (nr_gpr < GPR_COUNT) -+ nr_gpr++; -+ else -+ nr_stack++; -+ } -+ } -+} -+ -+static void -+invoke_copy_to_stack(PRUint64 * d, PRUint32 paramCount, nsXPTCVariant * s, -+ PRUint64 * gpregs, double * fpregs) -+{ -+ PRUint32 nr_gpr = 1; // skip one GP register for 'that' -+ PRUint32 nr_fpr = 0; -+ PRUint64 value; -+ -+ for (uint32 i = 0; i < paramCount; i++, s++) { -+ if (s->IsPtrData()) -+ value = (PRUint64) s->ptr; -+ else { -+ switch (s->type) { -+ case nsXPTType::T_FLOAT: break; -+ case nsXPTType::T_DOUBLE: break; -+ case nsXPTType::T_I8: value = s->val.i8; break; -+ case nsXPTType::T_I16: value = s->val.i16; break; -+ case nsXPTType::T_I32: value = s->val.i32; break; -+ case nsXPTType::T_I64: value = s->val.i64; break; -+ case nsXPTType::T_U8: value = s->val.u8; break; -+ case nsXPTType::T_U16: value = s->val.u16; break; -+ case nsXPTType::T_U32: value = s->val.u32; break; -+ case nsXPTType::T_U64: value = s->val.u64; break; -+ case nsXPTType::T_BOOL: value = s->val.b; break; -+ case nsXPTType::T_CHAR: value = s->val.c; break; -+ case nsXPTType::T_WCHAR: value = s->val.wc; break; -+ default: value = (PRUint64) s->val.p; break; -+ } -+ } -+ -+ if (!s->IsPtrData() && s->type == nsXPTType::T_DOUBLE) { -+ if (nr_fpr < FPR_COUNT) -+ fpregs[nr_fpr++] = s->val.d; -+ else { -+ *((double *)d) = s->val.d; -+ d++; -+ } -+ } -+ else if (!s->IsPtrData() && s->type == nsXPTType::T_FLOAT) { -+ if (nr_fpr < FPR_COUNT) -+ // The value in %xmm register is already prepared to -+ // be retrieved as a float.
